Explanation:
Okay, so I need to figure out the value of n in this magic square. Let me recall that a magic square has the same sum for each row, each column, and both main diagonals. The Asymptote code draws a 4x4 grid, but looking at the labels, it seems like the square is actually 3x3? Wait, no, the Asymptote code draws a 4x4 grid (from 0 to 3 in both directions), but labels are placed at positions like (.5, .5), which would be the center of each cell. Let me check the labels again:

The labels are:

- n-3 at (.5, .5) which is the center of the top-left cell (row 1, column 1)
- 3 at (.5, 1.5) which is the center of the middle-left cell (row 2, column 1)
- n+1 at (.5, 2.5) which is the center of the bottom-left cell (row 3, column 1)

Then:

- n+2 at (1.5, .5) which is center of top-middle cell (row 1, column 2)
- 2n-9 at (1.5, 1.5) which is middle-middle (row 2, column 2)
- 1 at (1.5, 2.5) which is bottom-middle (row 3, column 2)

Then:

- 2 at (2.5, .5) which is top-right cell (row 1, column 3)
- n at (2.5, 1.5) which is middle-right (row 2, column 3)
- n-1 at (2.5, 2.5) which is bottom-right (row 3, column 3)

Wait, so actually, the grid is 3x3? But the Asymptote code draws a 4x4 grid? Maybe there's a mistake here? Wait, no. Let me think again. If it's a 3x3 grid, the coordinates would be from 0 to 3 in both directions? No, for a 3x3 grid, coordinates would be 0 to 2 in both x and y. But the Asymptote code draws from 0 to 3, which would make 4x4 grid. But the labels are placed at positions like (.5, .5), which would be in the middle of each cell. So if you have a grid from 0 to 3, divided into 4 columns and 4 rows. But the labels are only placed in 3 columns and 3 rows? Wait, maybe it's a 3x3 grid? Maybe the Asymptote code is just drawing a 4x4 grid but only labeling 3x3 cells? Hmm, maybe it's a 3x3 magic square. Let me check the coordinates again:

The first label is at (.5, .5): that would be in the first cell (from (0,0) to (1,1)), so column 1, row 1.

Then (.5, 1.5): column 1, row 2.

Similarly, (.5, 2.5): column 1, row 3.

Similarly, the others are in columns 2 and 3. So yes, the magic square is 3x3. But the Asymptote code draws a 4x4 grid. Maybe it's a 3x3 grid with some extra lines? Maybe not important. Anyway, focusing on the labels.

So the magic square has the following numbers:

First column (leftmost column):

Row 1: n - 3

Row 2: 3

Row 3: n + 1

Second column (middle column):

Row 1: n + 2

Row 2: 2n - 9

Row 3: 1

Third column (rightmost column):

Row 1: 2

Row 2: n

Row 3: n - 1

So the square looks like:

[ n-3 | n+2 | 2 ]

[ 3 | 2n-9 | n ]

[ n+1 | 1 | n-1 ]

So I need to find n such that all rows, columns, and diagonals add up to the same sum.

Let me denote the magic sum as S.

First, let me compute the sum of the first row: (n - 3) + (n + 2) + 2 = 2n - 3 + 2 + 2? Wait:

Wait:

First row: (n - 3) + (n + 2) + 2 = n - 3 + n + 2 + 2 = 2n + ( -3 + 2 + 2 ) = 2n + 1.

So S = 2n + 1.

Alternatively, let's check second row:

Second row: 3 + (2n - 9) + n = 3 + 2n - 9 + n = 3n - 6.

So since it's a magic square, 2n + 1 = 3n - 6.

So solving 2n + 1 = 3n - 6 ⇒ 1 + 6 = 3n - 2n ⇒ n = 7.

Wait, is that possible? Let me check if n=7 satisfies other rows and columns.

But let me check third row:

Third row: (n + 1) + 1 + (n - 1) = n + 1 + 1 + n - 1 = 2n + 1. Which matches the first row. So if n=7, then the first row sum is 2*7 + 1 = 15, second row sum is 3*7 -6 = 21 -6 = 15, third row sum is same. So rows are okay.

But need to check columns and diagonals. Let me check columns.

First column: (n - 3) + 3 + (n + 1) = n -3 + 3 + n +1 = 2n +1. Which is same as S. For n=7, that's 15.

Second column: (n + 2) + (2n -9) + 1 = n + 2 + 2n -9 +1 = 3n -6. Which for n=7 is 21 -6=15. Okay.

Third column: 2 + n + (n -1) = 2 + n + n -1 = 2n +1. So same as before. For n=7, 15. So columns are okay.

Now check diagonals.

Main diagonal (top-left to bottom-right): (n - 3) + (2n -9) + (n -1) = n -3 + 2n -9 + n -1 = 4n -13. For n=7, 28 -13=15. Good.

Other diagonal (top-right to bottom-left): 2 + (2n -9) + (n +1) = 2 + 2n -9 + n +1 = 3n -6. For n=7, 21 -6=15. Perfect. So all diagonals are okay.

Therefore, seems like n=7 is the answer. Wait, but let me check the actual numbers with n=7.

Let me substitute n=7 into the square:

First column:

Row 1: 7 - 3 = 4

Row 2: 3

Row 3: 7 + 1 = 8

Second column:

Row 1: 7 + 2 = 9

Row 2: 2*7 -9 = 14 -9 =5

Row 3: 1

Third column:

Row 1: 2

Row 2: 7

Row 3: 7 -1 = 6

So the magic square is:

[4 | 9 | 2]

[3 | 5 | 7]

[8 | 1 | 6]

Let me check the rows:

First row: 4 + 9 + 2 = 15

Second row: 3 + 5 + 7 = 15

Third row: 8 + 1 + 6 = 15

Columns:

First column: 4 + 3 + 8 = 15

Second column: 9 + 5 + 1 = 15

Third column: 2 + 7 + 6 = 15

Diagonals:

4 + 5 + 6 = 15

2 + 5 + 8 = 15

Yes, this is a standard 3x3 magic square with magic sum 15. So n=7 is correct.

But wait, let me check if there is any other constraints or maybe I made a mistake in assuming the rows? Because in the magic square, all the rows, columns, and diagonals must be equal. However, when I first calculated the second row sum as 3n -6 and equated it to the first row sum of 2n +1, and solved for n=7, that gave me the answer, but maybe there are other equations?

But in this case, since all the rows, columns, and diagonals ended up giving the same equation, so maybe n=7 is indeed the correct answer.

Alternatively, maybe there's an error in the initial assumption? Let me check again.

Another way: Let's compute the magic sum S in another way. For example, the sum of all numbers in the square is 3S. Also, we can calculate the sum by adding all the numbers in terms of n.

Let me compute the total sum:

First row: (n -3) + (n +2) + 2 = 2n +1

Second row: 3 + (2n -9) + n = 3n -6

Third row: (n +1) +1 + (n -1) = 2n +1

Total sum: (2n +1) + (3n -6) + (2n +1) = 7n -4

But also, total sum is 3S. So 3S = 7n -4. But also, S can be expressed from first row: S = 2n +1. Therefore,

3*(2n +1) = 7n -4 ⇒ 6n +3 = 7n -4 ⇒ 3 +4 =7n -6n ⇒ n=7. Same answer. Therefore, seems consistent. So n=7 is correct.

Alternatively, let me check with another approach. Let me check the middle column. Middle column is 9, 5, 1 when n=7. Which adds to 15. Also, the middle row is 3, 5,7 which adds to 15. So yes, all checks out.

Wait, but just to make sure, let me check if there are any other constraints. For example, maybe some numbers need to be unique? But the problem doesn't state that. It just says it's a magic square. So even if numbers repeat, it's okay. In the standard magic square, numbers are 1-9, but here, with n=7, the numbers are 4,9,2,3,5,7,8,1,6 which are 1-9 except 4 is there, but duplicates? Wait, no, 1,2,3,4,5,6,7,8,9 all there. So yes, it's a standard magic square. So n=7 is correct.

Therefore, I think the answer is 7.

But just to make sure, let me check if there's another possible solution. Suppose I didn't check the columns and diagonals, and only equated the first two rows. Let me see:

First row sum: 2n +1.

Second row sum: 3n -6.

Setting them equal gives n=7. Then third row sum is 2n +1, which matches. Then columns and diagonals also check out. So no other solution. Since we have a unique solution, n=7 is the answer. Therefore, I think the answer is 7.

**Final Answer**
\boxed{7}

To solve for $ n $ in the given magic square, we need to take advantage of the key property of all magic squares: **the sum of every row, every column, and both main diagonals are equal**.

### Step 1: Understand the Grid

The grid is a **3x3** magic square with the following variables placed at specific positions:

|           | Col 1        | Col 2        | Col 3        |
|-----------|--------------|--------------|--------------|
| Row 1     | $ n - 3 $  | $ n + 2 $  | $ 2 $      |
| Row 2     | $ 3 $      | $ 2n - 9 $ | $ n $      |
| Row 3     | $ n + 1 $  | $ 1 $      | $ n - 1 $  |

---

### Step 2: Express the Sum of Each Row

Let’s compute the sum of the **first row**:

$$
(n - 3) + (n + 2) + 2 = 2n + 1
$$

Now, compute the **second row**:

$$
3 + (2n - 9) + n = 3 + 2n - 9 + n = 3n - 6
$$

Set the two rows equal to each other (since they must sum to the same magic constant $ S $):

$$
2n + 1 = 3n - 6
$$

Solving for $ n $:

$$
1 + 6 = 3n - 2n \Rightarrow n = 7
$$

---

### Step 3: Verify the Solution

Plug $ n = 7 $ into all rows, columns, and diagonals to ensure that all sums are equal.

#### Rows:

- Row 1: $ 7 - 3 = 4 $, $ 7 + 2 = 9 $, $ 2 $ → Sum = $ 4 + 9 + 2 = 15 $
- Row 2: $ 3 $, $ 2(7) - 9 = 5 $, $ 7 $ → Sum = $ 3 + 5 + 7 = 15 $
- Row 3: $ 7 + 1 = 8 $, $ 1 $, $ 7 - 1 = 6 $ → Sum = $ 8 + 1 + 6 = 15 $

All rows sum to 15, so that’s consistent.

#### Columns:

- Col 1: $ 4 + 3 + 8 = 15 $
- Col 2: $ 9 + 5 + 1 = 15 $
- Col 3: $ 2 + 7 + 6 = 15 $

#### Diagonals:

- Main diagonal (top-left to bottom-right): $ 4 + 5 + 6 = 15 $
- Other diagonal (top-right to bottom-left): $ 2 + 5 + 8 = 15 $

---

### Step 4: Final Check and Uniqueness

All rows, columns, and diagonals sum to 15, and all are equal. Therefore, the value of $ n = 7 $ satisfies all constraints of a magic square.

The configuration of the magic square with $ n = 7 $ is the classic 3x3 magic square containing the numbers 1 through 9, arranged so that all lines sum to 15.

Explanation:
Okay, so I need to figure out the value of n in this magic square. Let me recall that a magic square has the same sum for each row, each column, and both main diagonals. The Asymptote code draws a 4x4 grid, but looking at the labels, it seems like the square is actually 3x3? Wait, no, the Asymptote code draws a 4x4 grid (from 0 to 3 in both directions), but labels are placed at positions like (.5, .5), which would be the center of each cell. Let me check the labels again:

The labels are:

- n-3 at (.5, .5) which is the center of the top-left cell (row 1, column 1)
- 3 at (.5, 1.5) which is the center of the middle-left cell (row 2, column 1)
- n+1 at (.5, 2.5) which is the center of the bottom-left cell (row 3, column 1)

Then:

- n+2 at (1.5, .5) which is center of top-middle cell (row 1, column 2)
- 2n-9 at (1.5, 1.5) which is middle-middle (row 2, column 2)
- 1 at (1.5, 2.5) which is bottom-middle (row 3, column 2)

Then:

- 2 at (2.5, .5) which is top-right cell (row 1, column 3)
- n at (2.5, 1.5) which is middle-right (row 2, column 3)
- n-1 at (2.5, 2.5) which is bottom-right (row 3, column 3)

Wait, so actually, the grid is 3x3? But the Asymptote code draws a 4x4 grid? Maybe there's a mistake here? Wait, no. Let me think again. If it's a 3x3 grid, the coordinates would be from 0 to 3 in both directions? No, for a 3x3 grid, coordinates would be 0 to 2 in both x and y. But the Asymptote code draws from 0 to 3, which would make 4x4 grid. But the labels are placed at positions like (.5, .5), which would be in the middle of each cell. So if you have a grid from 0 to 3, divided into 4 columns and 4 rows. But the labels are only placed in 3 columns and 3 rows? Wait, maybe it's a 3x3 grid? Maybe the Asymptote code is just drawing a 4x4 grid but only labeling 3x3 cells? Hmm, maybe it's a 3x3 magic square. Let me check the coordinates again:

The first label is at (.5, .5): that would be in the first cell (from (0,0) to (1,1)), so column 1, row 1.

Then (.5, 1.5): column 1, row 2.

Similarly, (.5, 2.5): column 1, row 3.

Similarly, the others are in columns 2 and 3. So yes, the magic square is 3x3. But the Asymptote code draws a 4x4 grid. Maybe it's a 3x3 grid with some extra lines? Maybe not important. Anyway, focusing on the labels.

So the magic square has the following numbers:

First column (leftmost column):

Row 1: n - 3

Row 2: 3

Row 3: n + 1

Second column (middle column):

Row 1: n + 2

Row 2: 2n - 9

Row 3: 1

Third column (rightmost column):

Row 1: 2

Row 2: n

Row 3: n - 1

So the square looks like:

[ n-3 | n+2 | 2 ]

[ 3 | 2n-9 | n ]

[ n+1 | 1 | n-1 ]

So I need to find n such that all rows, columns, and diagonals add up to the same sum.

Let me denote the magic sum as S.

First, let me compute the sum of the first row: (n - 3) + (n + 2) + 2 = 2n - 3 + 2 + 2? Wait:

Wait:

First row: (n - 3) + (n + 2) + 2 = n - 3 + n + 2 + 2 = 2n + ( -3 + 2 + 2 ) = 2n + 1.

So S = 2n + 1.

Alternatively, let's check second row:

Second row: 3 + (2n - 9) + n = 3 + 2n - 9 + n = 3n - 6.

So since it's a magic square, 2n + 1 = 3n - 6.

So solving 2n + 1 = 3n - 6 ⇒ 1 + 6 = 3n - 2n ⇒ n = 7.

Wait, is that possible? Let me check if n=7 satisfies other rows and columns.

But let me check third row:

Third row: (n + 1) + 1 + (n - 1) = n + 1 + 1 + n - 1 = 2n + 1. Which matches the first row. So if n=7, then the first row sum is 2*7 + 1 = 15, second row sum is 3*7 -6 = 21 -6 = 15, third row sum is same. So rows are okay.

But need to check columns and diagonals. Let me check columns.

First column: (n - 3) + 3 + (n + 1) = n -3 + 3 + n +1 = 2n +1. Which is same as S. For n=7, that's 15.

Second column: (n + 2) + (2n -9) + 1 = n + 2 + 2n -9 +1 = 3n -6. Which for n=7 is 21 -6=15. Okay.

Third column: 2 + n + (n -1) = 2 + n + n -1 = 2n +1. So same as before. For n=7, 15. So columns are okay.

Now check diagonals.

Main diagonal (top-left to bottom-right): (n - 3) + (2n -9) + (n -1) = n -3 + 2n -9 + n -1 = 4n -13. For n=7, 28 -13=15. Good.

Other diagonal (top-right to bottom-left): 2 + (2n -9) + (n +1) = 2 + 2n -9 + n +1 = 3n -6. For n=7, 21 -6=15. Perfect. So all diagonals are okay.

Therefore, seems like n=7 is the answer. Wait, but let me check the actual numbers with n=7.

Let me substitute n=7 into the square:

First column:

Row 1: 7 - 3 = 4

Row 2: 3

Row 3: 7 + 1 = 8

Second column:

Row 1: 7 + 2 = 9

Row 2: 2*7 -9 = 14 -9 =5

Row 3: 1

Third column:

Row 1: 2

Row 2: 7

Row 3: 7 -1 = 6

So the magic square is:

[4 | 9 | 2]

[3 | 5 | 7]

[8 | 1 | 6]

Let me check the rows:

First row: 4 + 9 + 2 = 15

Second row: 3 + 5 + 7 = 15

Third row: 8 + 1 + 6 = 15

Columns:

First column: 4 + 3 + 8 = 15

Second column: 9 + 5 + 1 = 15

Third column: 2 + 7 + 6 = 15

Diagonals:

4 + 5 + 6 = 15

2 + 5 + 8 = 15

Yes, this is a standard 3x3 magic square with magic sum 15. So n=7 is correct.

But wait, let me check if there is any other constraints or maybe I made a mistake in assuming the rows? Because in the magic square, all the rows, columns, and diagonals must be equal. However, when I first calculated the second row sum as 3n -6 and equated it to the first row sum of 2n +1, and solved for n=7, that gave me the answer, but maybe there are other equations?

But in this case, since all the rows, columns, and diagonals ended up giving the same equation, so maybe n=7 is indeed the correct answer.

Alternatively, maybe there's an error in the initial assumption? Let me check again.

Another way: Let's compute the magic sum S in another way. For example, the sum of all numbers in the square is 3S. Also, we can calculate the sum by adding all the numbers in terms of n.

Let me compute the total sum:

First row: (n -3) + (n +2) + 2 = 2n +1

Second row: 3 + (2n -9) + n = 3n -6

Third row: (n +1) +1 + (n -1) = 2n +1

Total sum: (2n +1) + (3n -6) + (2n +1) = 7n -4

But also, total sum is 3S. So 3S = 7n -4. But also, S can be expressed from first row: S = 2n +1. Therefore,

3*(2n +1) = 7n -4 ⇒ 6n +3 = 7n -4 ⇒ 3 +4 =7n -6n ⇒ n=7. Same answer. Therefore, seems consistent. So n=7 is correct.

Alternatively, let me check with another approach. Let me check the middle column. Middle column is 9, 5, 1 when n=7. Which adds to 15. Also, the middle row is 3, 5,7 which adds to 15. So yes, all checks out.

Wait, but just to make sure, let me check if there are any other constraints. For example, maybe some numbers need to be unique? But the problem doesn't state that. It just says it's a magic square. So even if numbers repeat, it's okay. In the standard magic square, numbers are 1-9, but here, with n=7, the numbers are 4,9,2,3,5,7,8,1,6 which are 1-9 except 4 is there, but duplicates? Wait, no, 1,2,3,4,5,6,7,8,9 all there. So yes, it's a standard magic square. So n=7 is correct.

Therefore, I think the answer is 7.

But just to make sure, let me check if there's another possible solution. Suppose I didn't check the columns and diagonals, and only equated the first two rows. Let me see:

First row sum: 2n +1.

Second row sum: 3n -6.

Setting them equal gives n=7. Then third row sum is 2n +1, which matches. Then columns and diagonals also check out. So no other solution. Since we have a unique solution, n=7 is the answer. Therefore, I think the answer is 7.

**Final Answer**
\boxed{7}

To solve for $ n $ in the given magic square, we need to take advantage of the key property of all magic squares: **the sum of every row, every column, and both main diagonals are equal**.

### Step 1: Understand the Grid

The grid is a **3x3** magic square with the following variables placed at specific positions:

|           | Col 1        | Col 2        | Col 3        |
|-----------|--------------|--------------|--------------|
| Row 1     | $ n - 3 $  | $ n + 2 $  | $ 2 $      |
| Row 2     | $ 3 $      | $ 2n - 9 $ | $ n $      |
| Row 3     | $ n + 1 $  | $ 1 $      | $ n - 1 $  |

---

### Step 2: Express the Sum of Each Row

Let’s compute the sum of the **first row**:

$$
(n - 3) + (n + 2) + 2 = 2n + 1
$$

Now, compute the **second row**:

$$
3 + (2n - 9) + n = 3 + 2n - 9 + n = 3n - 6
$$

Set the two rows equal to each other (since they must sum to the same magic constant $ S $):

$$
2n + 1 = 3n - 6
$$

Solving for $ n $:

$$
1 + 6 = 3n - 2n \Rightarrow n = 7
$$

---

### Step 3: Verify the Solution

Plug $ n = 7 $ into all rows, columns, and diagonals to ensure that all sums are equal.

#### Rows:

- Row 1: $ 7 - 3 = 4 $, $ 7 + 2 = 9 $, $ 2 $ → Sum = $ 4 + 9 + 2 = 15 $
- Row 2: $ 3 $, $ 2(7) - 9 = 5 $, $ 7 $ → Sum = $ 3 + 5 + 7 = 15 $
- Row 3: $ 7 + 1 = 8 $, $ 1 $, $ 7 - 1 = 6 $ → Sum = $ 8 + 1 + 6 = 15 $

All rows sum to 15, so that’s consistent.

#### Columns:

- Col 1: $ 4 + 3 + 8 = 15 $
- Col 2: $ 9 + 5 + 1 = 15 $
- Col 3: $ 2 + 7 + 6 = 15 $

#### Diagonals:

- Main diagonal (top-left to bottom-right): $ 4 + 5 + 6 = 15 $
- Other diagonal (top-right to bottom-left): $ 2 + 5 + 8 = 15 $

---

### Step 4: Final Check and Uniqueness

All rows, columns, and diagonals sum to 15, and all are equal. Therefore, the value of $ n = 7 $ satisfies all constraints of a magic square.

The configuration of the magic square with $ n = 7 $ is the classic 3x3 magic square containing the numbers 1 through 9, arranged so that all lines sum to 15.

---

### Final Answer

$$
\boxed{7}
$$

Solution:
First, we can evaluate the sum across the first row, which gives $(n+1)+1+(n-1)=2n+1$.  Evaluate the sum of the entries across the second row, $3+(2n-9)+n=3n-6$. Now, since we have a magic square, these two sums are equal.  So $2n+1=3n-6$. Isolating $n$, we obtain $n = \boxed{7}$.

The square will look like: [asy] size(2cm);

Explanation:
Okay, let's tackle this problem step by step. First, let me try to understand all the given information and what needs to be found.

We have an unfair six-sided die. The die has faces numbered 1 through 6. The key points are:

1. The probability of obtaining face F is greater than 1/6.
2. The probability of obtaining the face opposite to F is less than 1/6.
3. The probability of each of the other four faces is exactly 1/6.
4. The sum of the numbers on each pair of opposite faces is 7. So, for example, 1 is opposite 6, 2 opposite 5, 3 opposite 4.

When two such dice are rolled, the probability of getting a sum of 7 is 47/288. We need to find the probability of face F, express it as a reduced fraction m/n, and then find m + n.

First, let's note the opposite faces. Since the sum of each pair is 7, the pairs are (1,6), (2,5), (3,4). Therefore, if F is one of these numbers, its opposite face is 7 - F.

Let me denote the probability of face F as p. Then, the probability of its opposite face is q, which is less than 1/6. The other four faces have probability 1/6 each.

Since the die has six faces, the total probability must sum to 1. Therefore:

p + q + 4*(1/6) = 1

Simplify:

p + q + 2/3 = 1 => p + q = 1 - 2/3 = 1/3

So, p + q = 1/3. Also, we know p > 1/6 and q < 1/6. Since p + q = 1/3, if q were equal to 1/6, p would be 1/6. But since q < 1/6, p must be greater than 1/6. Similarly, since p + q = 1/3, if p were equal to 1/6, q would be 1/6, but p is greater than 1/6, so q is less than 1/6. That checks out.

Now, moving on to the probability of getting a sum of 7 when two dice are rolled. Let's think about how that sum can be achieved. The sum of 7 can be obtained in several ways when rolling two dice:

Each die has pairs of opposite faces summing to 7. So, for example, if one die shows 1, the other needs to show 6 to make 7, and so on. However, since the dice are unfair, the probabilities of each face are different.

But let's think about all possible pairs that sum to 7. Let's consider the pairs (1,6), (2,5), (3,4). For each of these pairs, the probability of rolling the first number on one die and the second on the other die.

However, when rolling two dice, there are two ways for each pair: first die shows the first number, second die shows the second number; or first die shows the second number, second die shows the first number. However, if the two numbers are on opposite faces, but the dice are different, so each pair contributes twice unless the numbers are the same. But in our case, since all numbers on each die are distinct (since it's a die), so for each pair (a, b) where a ≠ b, there are two ways to get their sum. However, in our case, since the numbers are 1-6, and the pairs that sum to 7 are each unique.

But wait, when calculating the probability of getting a sum of 7, we have to consider all possible combinations. Let me think.

Let me denote the first die as Die A and the second die as Die B. Then, the total probability of getting a sum of 7 is the sum over all pairs (i, j) where i + j = 7, of P(A = i) * P(B = j).

So, for each such pair, we have:

For (1,6): P(A=1)*P(B=6) + P(A=6)*P(B=1)

Similarly for (2,5): P(A=2)*P(B=5) + P(A=5)*P(B=2)

Similarly for (3,4): P(A=3)*P(B=4) + P(A=4)*P(B=3)

Additionally, for the pair (F, opposite(F)), since F is one face, and opposite(F) is another face. Wait, but since the pairs that sum to 7 are fixed as (1,6), (2,5), (3,4). So unless F is one of these numbers. Wait, F is a face, so its opposite face is 7 - F. Therefore, (F, 7 - F) is one of the pairs that sum to 7. So, depending on what F is, the pair (F, opposite(F)) is one of the three pairs.

But the problem states that when rolling two such dice, the probability of getting a sum of 7 is 47/288. Therefore, we need to calculate that probability in terms of p and q, and then solve for p.

But first, let me think: since the die has probabilities p for face F, q for its opposite face, and 1/6 for the other four. But which numbers are F and its opposite? Let me suppose that F is one of the numbers, say, for example, 1. Then its opposite is 6. But then, the probability of 1 is p, probability of 6 is q. The other numbers (2, 3, 4, 5) have probability 1/6. But maybe F is not 1? Wait, but since the die is arbitrary, but the pairs are fixed as (1,6), (2,5), (3,4). So regardless of which face F is, its opposite is fixed. However, the problem states that the probability of face F is greater than 1/6, and the opposite face is less than 1/6. So, F could be any of the numbers 1-6. However, since the problem doesn't specify which face F is, but since the sum of the numbers on opposite faces is 7, and the probability distribution depends on F. However, since the problem is symmetric with respect to the pairs, perhaps the value of p is same regardless of which pair F is in? Wait, no, because depending on which pair F is in, the other numbers would vary. Wait, but the problem says "the probability of obtaining face F is greater than 1/6, the probability of obtaining the face opposite face F is less than 1/6, the probability of obtaining each of the other faces is 1/6". So, if F is part of a pair, then the other numbers are fixed. For example, if F is 1, then the opposite face is 6. The other numbers are 2, 3, 4, 5, which have probability 1/6 each. If F is 2, then opposite face is 5, and other numbers are 1,3,4,6. Similarly for others. However, since the sum of probabilities must be 1, regardless of which pair F is in, the equations will be the same. Therefore, perhaps the result is independent of which pair F is in? Therefore, maybe we can assume without loss of generality that F is 1, for simplicity. Let me check.

Let me suppose that F is 1. Therefore, opposite face is 6. Then, the probability of 1 is p, probability of 6 is q. The other faces (2,3,4,5) each have probability 1/6. Then, when we compute the probability of getting a sum of 7 with two such dice, we need to consider all the pairs that sum to 7.

So, pairs are (1,6), (2,5), (3,4). So, for each pair, the probability is:

For (1,6): P(1 on first die) * P(6 on second die) + P(6 on first die) * P(1 on second die) = p*q + q*p = 2p*q

For (2,5): P(2 on first die) * P(5 on second die) + P(5 on first die) * P(2 on second die). Since 2 and 5 each have probability 1/6, so this is (1/6)*(1/6) + (1/6)*(1/6) = 2*(1/36) = 1/18

Similarly for (3,4): same as (2,5), so another 1/18.

Therefore, total probability of sum 7 is 2pq + 1/18 + 1/18 = 2pq + 1/9.

But according to the problem, this probability is 47/288. So:

2pq + 1/9 = 47/288

Let me compute 1/9 as 32/288. Therefore:

2pq + 32/288 = 47/288 => 2pq = 47/288 - 32/288 = 15/288 = 5/96 => pq = 5/192

But earlier, we had p + q = 1/3.

So now, we have:

p + q = 1/3

pq = 5/192

Therefore, we can set up a quadratic equation. Let me denote p and q as roots of x² - (p + q)x + pq = 0 => x² - (1/3)x + 5/192 = 0.

Multiply through by 192 to eliminate denominators:

192x² - 64x + 5 = 0

Let me check that:

Original equation: x² - (1/3)x + 5/192 = 0

Multiply by 192:

192x² - 64x + 5 = 0. Yes.

Now, solving this quadratic equation for x:

Discriminant D = b² - 4ac = (-64)² - 4*192*5 = 4096 - 3840 = 256

Square root of D is 16.

Solutions:

x = [64 ± 16]/(2*192) = [64 ± 16]/384

So,

First solution: (64 + 16)/384 = 80/384 = 5/24 ≈ 0.2083

Second solution: (64 - 16)/384 = 48/384 = 1/8 = 0.125

Therefore, the solutions are p = 5/24 and q = 1/8, or p = 1/8 and q = 5/24.

But remember, p is the probability of face F, which is greater than 1/6 ≈ 0.1667. Let's check:

5/24 ≈ 0.2083 > 1/6 (≈ 0.1667), so that works.

1/8 = 0.125 < 1/6 ≈ 0.1667, so that's q. Therefore, since p is the probability of F, which is greater than 1/6, p must be 5/24. Therefore, the answer is 5/24, so m = 5 and n = 24, m + n = 29.

Wait, but hold on. Let me check again. Wait, if F is 1, then p = probability of 1 is 5/24, which is greater than 1/6, and q = probability of 6 is 1/8, which is less than 1/6, which fits. But what if F was another face?

Wait, for example, suppose that F is 2. Then, the opposite face is 5, so p would be the probability of 2, which is greater than 1/6, and q is probability of 5, which is less than 1/6. Then, when computing the probability of sum of 7, we would have:

For the pair (2,5): same as before. Wait, let me recalculate the total probability of sum 7 in this case.

But if F is 2, then:

The die has:

Probability of 2: p

Probability of 5: q

Other faces (1, 3, 4, 6) have probability 1/6 each.

Therefore, when computing the sum of 7, the pairs are (1,6), (2,5), (3,4). Therefore, the same as before. For each of these pairs:

(1,6): same as before, each with probability 1/6. So the contribution is 2*(1/6 * 1/6) = 2*(1/36) = 1/18

Similarly for (3,4): same as above, 1/18

For (2,5): probability is p*q + q*p = 2pq.

Therefore, same as before. Therefore, regardless of which pair F is in, the total probability is 2pq + 1/9. Hence, same equation. Therefore, regardless of which face F is, the result is same. Therefore, p is 5/24. Therefore, answer is 5/24, m + n = 29.

Wait, but before I conclude, let me check whether there could be any other possibilities. For example, maybe the die's probabilities for the other faces are not all 1/6?

Wait, no. The problem states: "the probability of obtaining each of the other faces is 1/6". So, if F is one face, and its opposite is another face, then the other four faces (the ones not F nor opposite(F)) have probability 1/6 each. So regardless of which pair F is in, the calculation is same. Hence, the same equation.

But let me check the arithmetic again. Let me recast the equations.

Given that total probability is 1:

p + q + 4*(1/6) = 1 => p + q = 1 - 2/3 = 1/3. Correct.

Then, the probability of getting a sum of 7 is:

For the pair (F, opposite(F)): 2*p*q

For the other pairs (which are (a, b) where a and b are not F or its opposite, and each of those has probability 1/6. So for each of the other two pairs (since there are three pairs total: (F, opposite(F)), and the other two pairs), each of those pairs contributes 2*(1/6 * 1/6) = 2*(1/36) = 1/18 per pair. Since there are two such pairs, total contribution is 2*(1/18) = 1/9.

Hence total probability is 2pq + 1/9 = 47/288.

Then solving:

2pq = 47/288 - 1/9 = 47/288 - 32/288 = 15/288 = 5/96. Hence pq = 5/192. Then, solving p + q = 1/3 and pq = 5/192. So quadratic equation x² - (1/3)x + 5/192 = 0. Multiply by 192: 192x² - 64x + 5 = 0. Discriminant: 64² - 4*192*5 = 4096 - 3840 = 256. sqrt(256) = 16. So solutions: [64 ±16]/(2*192). So (64 + 16)/384 = 80/384 = 5/24, and (64 -16)/384 = 48/384 = 1/8. So p is 5/24 (since p > 1/6) and q is 1/8.

Therefore, the probability of F is 5/24. 5 and 24 are coprime? 5 is prime, 24 is 2^3*3. 5 doesn't divide 24. So yes, reduced fraction. Therefore, m + n = 5 + 24 = 29.

Wait, but let me check again the calculation of 47/288 - 1/9. Let me verify:

Convert 1/9 to 32/288, because 1/9 = 32/288? Wait:

Wait, 1/9 = 32/288? Let me check. 288 divided by 9 is 32. Yes, because 9*32 = 288. So yes, 1/9 = 32/288. Then 47/288 - 32/288 = 15/288. Simplify: divide numerator and denominator by 3: 5/96. Yes, correct. So pq = 5/96? Wait, no:

Wait, 2pq = 15/288 => pq = 15/576 = 5/192? Wait, 15 divided by 2 is 7.5? Wait, wait:

Wait, 2pq = 15/288 => pq = (15/288)/2 = 15/576 = 5/192. Yes, correct.

Therefore, solving quadratic equation is correct. Therefore, answer 5/24. So m + n = 29. Therefore, I think the answer is 29.

But just to be thorough, let me check if there's another way that the probability of getting sum 7 could be calculated, perhaps I missed some combinations?

Wait, for example, suppose that the face F is 1, and its opposite is 6. Suppose that when rolling two dice, there are other ways to get a sum of 7. Wait, no. The sum of 7 can only be achieved by the pairs (1,6), (2,5), (3,4). So if you roll two dice, the only way to get 7 is to have one die show a number from one pair and the other die show the opposite. Therefore, the calculation is correct.

Alternatively, let's think about all possible combinations:

Total number of possible outcomes? Well, since the die is unfair, the probability isn't uniform, but the probability of each outcome is the product of the individual probabilities. So, the total probability of getting sum 7 is as above.

Alternatively, suppose we think of the probability as follows:

Each die has probabilities:

For face F: p

For opposite face of F: q

For other four faces: 1/6 each.

Therefore, for two dice, the probability of (F, opposite(F)) is p*q, and (opposite(F), F) is q*p, so total 2pq. For the pairs (a, b) where a and b are not F or opposite(F), each pair contributes 2*(1/6 * 1/6) = 1/18. Since there are two such pairs, total 2*(1/18) = 1/9. Therefore, total probability 2pq + 1/9. So that's correct.

Therefore, solving gives p = 5/24. Hence, answer 5 + 24 = 29.

But just to check, let me compute the probability with p = 5/24 and q = 1/8.

Compute 2pq + 1/9:

2*(5/24)*(1/8) + 1/9 = 2*(5/192) + 1/9 = 10/192 + 1/9 = 5/96 + 1/9.

Convert to common denominator, which is 288:

5/96 = 15/288, 1/9 = 32/288. Total: 15 + 32 = 47/288. Which matches the given probability. Perfect.

Therefore, the answer is indeed 5/24. Therefore, m + n = 5 + 24 = 29.

I think that's solid. So I think the answer is 29.

**Final Answer**
\boxed{29}

To solve the problem, we consider the behavior of a specific unfair six-sided die. The die has the following characteristics:

- Each face is labeled with a number from 1 to 6.
- Opposite faces sum to 7. Thus, the pairs are (1,6), (2,5), and (3,4).
- A face $ F $ has a probability $ p $, which is **greater than** $ \frac{1}{6} $.
- The face opposite to $ F $ has probability $ q $, which is **less than** $ \frac{1}{6} $.
- The four other faces each have probability $ \frac{1}{6} $.
- The total sum of probabilities is 1:
  $$
  p + q + 4 \cdot \frac{1}{6} = 1 \Rightarrow p + q = \frac{1}{3}
  $$

We are given that when rolling two such dice, the probability of obtaining a sum of 7 is $ \frac{47}{288} $. We aim to find the probability $ p $ of face $ F $, and then compute $ m + n $ where $ p = \frac{m}{n} $ in simplest form.

---

### Step 1: Express Probability of Sum = 7

To compute the probability of getting a sum of 7 with two dice, we consider all pairs of numbers $ (i, j) $ such that $ i + j = 7 $. These are the pairs:

- $ (1,6) $
- $ (2,5) $
- $ (3,4) $

Each of these contributes to the total sum of 7 in two ways for distinct $ i $ and $ j $:
- $ i $ on first die, $ j $ on second die
- $ j $ on first die, $ i $ on second die

So, the probability of each pair (like $ (1,6) $) is:
$$
P(i=j) + P(j=i) = 2 \cdot P(i) \cdot P(j)
$$

Now, let’s examine how the pairs contribute to the total probability of getting a sum of 7.

- The pair $ (F, \text{opposite}(F)) $: has probability $ 2pq $
- The other two pairs (e.g., if $ F = 1 $, then $ (2,5) $ and $ (3,4) $), each contribute $ 2 \cdot \frac{1}{6} \cdot \frac{1}{6} = \frac{2}{36} = \frac{1}{18} $

So the total probability of getting a sum of 7 is:
$$
P(\text{sum} = 7) = 2pq + \frac{1}{18} + \frac{1}{18} = 2pq + \frac{1}{9}
$$
This expression is universal regardless of which face $ F $ is chosen, due to the symmetry of the die's probability distribution.

We are told that:
$$
2pq + \frac{1}{9} = \frac{47}{288}
$$

---

### Step 2: Solve for $ p $ and $ q $

First, solve for $ 2pq $:
$$
2pq = \frac{47}{288} - \frac{1}{9} = \frac{47}{288} - \frac{32}{288} = \frac{15}{288} = \frac{5}{96}
\Rightarrow pq = \frac{5}{192}
$$

We also know that:
$$
p + q = \frac{1}{3}
$$

We now solve the system:
$$
p + q = \frac{1}{3}, \quad pq = \frac{5}{192}
$$

These are the roots of the quadratic:
$$
x^2 - \left(\frac{1}{3}\right)x + \frac{5}{192} = 0
$$

Multiply through by 192 to eliminate denominators:
$$
192x^2 - 64x + 5 = 0
$$

Now find the roots using the quadratic formula:
$$
x = \frac{64 \pm \sqrt{(-64)^2 - 4(192)(5)}}{2(192)} = \frac{64 \pm \sqrt{4096 - 3840}}{384}
= \frac{64 \pm \sqrt{256}}{384}
= \frac{64 \pm 16}{384}
$$

Two roots:
$$
x_1 = \frac{80}{384} = \frac{5}{24}, \quad x_2 = \frac{48}{384} = \frac{1}{8}
$$

Now assign:
- Since $ p > \frac{1}{6} $, and $ \frac{5}{24} \approx 0.208 $, which is greater than $ \frac{1}{6} \approx 0.166 $, we assign $ p = \frac{5}{24} $
- Therefore, $ q = \frac{1}{8} $

---

### Step 3: Final Answer

Given that the probability of face $ F $ is $ p = \frac{5}{24} $, we express this as a reduced fraction $ m/n $, where $ m = 5 $ and $ n = 24 $. Since 5 and 24 are relatively prime, we find:
$$
m + n = 5 + 24 = \boxed{29}
$$

[Assistant]
Explanation:
Okay, let's tackle this problem step by step. First, let me try to understand all the given information and what needs to be found.

We have an unfair six-sided die. The die has faces numbered 1 through 6. The key points are:

1. The probability of obtaining face F is greater than 1/6.
2. The probability of obtaining the face opposite to F is less than 1/6.
3. The probability of each of the other four faces is exactly 1/6.
4. The sum of the numbers on each pair of opposite faces is 7. So, for example, 1 is opposite 6, 2 opposite 5, 3 opposite 4.

When two such dice are rolled, the probability of getting a sum of 7 is 47/288. We need to find the probability of face F, express it as a reduced fraction m/n, and then find m + n.

First, let's note the opposite faces. Since the sum of each pair is 7, the pairs are (1,6), (2,5), (3,4). Therefore, if F is one of these numbers, its opposite face is 7 - F.

Let me denote the probability of face F as p. Then, the probability of its opposite face is q, which is less than 1/6. The other four faces have probability 1/6 each.

Since the die has six faces, the total probability must sum to 1. Therefore:

p + q + 4*(1/6) = 1

Simplify:

p + q + 2/3 = 1 => p + q = 1 - 2/3 = 1/3

So, p + q = 1/3. Also, we know p > 1/6 and q < 1/6. Since p + q = 1/3, if q were equal to 1/6, p would be 1/6. But since q < 1/6, p must be greater than 1/6. Similarly, since p + q = 1/3, if p were equal to 1/6, q would be 1/6, but p is greater than 1/6, so q is less than 1/6. That checks out.

Now, moving on to the probability of getting a sum of 7 when two dice are rolled. Let's think about how that sum can be achieved. The sum of 7 can be obtained in several ways when rolling two dice:

Each die has pairs of opposite faces summing to 7. So, for example, if one die shows 1, the other needs to show 6 to make 7, and so on. However, since the dice are unfair, the probabilities of each face are different.

But let's think about all possible pairs that sum to 7. Let's consider the pairs (1,6), (2,5), (3,4). For each of these pairs, the probability of rolling the first number on one die and the second on the other die.

However, when rolling two dice, there are two ways for each pair: first die shows the first number, second die shows the second number; or first die shows the second number, second die shows the first number. However, if the two numbers are on opposite faces, but the dice are different, so each pair contributes twice unless the numbers are the same. But in our case, since all numbers on each die are distinct (since it's a die), so for each pair (a, b) where a ≠ b, there are two ways to get their sum. However, in our case, since the numbers are 1-6, and the pairs that sum to 7 are each unique.

But wait, when calculating the probability of getting a sum of 7, we have to consider all possible combinations. Let me think.

Let me denote the first die as Die A and the second die as Die B. Then, the total probability of getting a sum of 7 is the sum over all pairs (i, j) where i + j = 7, of P(A = i) * P(B = j).

So, for each such pair, we have:

For (1,6): P(A=1)*P(B=6) + P(A=6)*P(B=1)

Similarly for (2,5): P(A=2)*P(B=5) + P(A=5)*P(B=2)

Similarly for (3,4): P(A=3)*P(B=4) + P(A=4)*P(B=3)

Additionally, for the pair (F, opposite(F)), since F is one face, and opposite(F) is another face. Wait, but since the pairs that sum to 7 are fixed as (1,6), (2,5), (3,4). So unless F is one of these numbers. Wait, F is a face, so its opposite face is 7 - F. Therefore, (F, 7 - F) is one of the pairs that sum to 7. So, depending on what F is, the pair (F, opposite(F)) is one of the three pairs.

But the problem states that when rolling two such dice, the probability of getting a sum of 7 is 47/288. Therefore, we need to calculate that probability in terms of p and q, and then solve for p.

But first, let me think: since the die has probabilities p for face F, q for its opposite face, and 1/6 for the other four. But which numbers are F and its opposite? Let me suppose that F is one of the numbers, say, for example, 1. Then its opposite is 6. But then, the probability of 1 is p, probability of 6 is q. The other numbers (2, 3, 4, 5) have probability 1/6. But maybe F is not 1? Wait, but since the die is arbitrary, but the pairs are fixed as (1,6), (2,5), (3,4). So regardless of which face F is, its opposite is fixed. However, the problem states that the probability of face F is greater than 1/6, and the opposite face is less than 1/6. So, F could be any of the numbers 1-6. However, since the problem doesn't specify which face F is, but since the sum of the numbers on opposite faces is 7, and the probability distribution depends on F. However, since the problem is symmetric with respect to the pairs, perhaps the value of p is same regardless of which pair F is in? Wait, no, because depending on which pair F is in, the other numbers would vary. Wait, but the problem says "the probability of obtaining face F is greater than 1/6, the probability of obtaining the face opposite face F is less than 1/6, the probability of obtaining each of the other faces is 1/6". So, if F is part of a pair, then the other numbers are fixed. For example, if F is 1, then the opposite face is 6. The other numbers are 2, 3, 4, 5, which have probability 1/6 each. If F is 2, then opposite face is 5, and other numbers are 1,3,4,6. Similarly for others. However, since the sum of probabilities must be 1, regardless of which pair F is in, the equations will be the same. Therefore, perhaps the result is independent of which pair F is in? Therefore, maybe we can assume without loss of generality that F is 1, for simplicity. Let me check.

Let me suppose that F is 1. Therefore, opposite face is 6. Then, the probability of 1 is p, probability of 6 is q. The other faces (2,3,4,5) each have probability 1/6. Then, when we compute the probability of getting a sum of 7 with two such dice, we need to consider all the pairs that sum to 7.

So, pairs are (1,6), (2,5), (3,4). So, for each pair, the probability is:

For (1,6): P(1 on first die) * P(6 on second die) + P(6 on first die) * P(1 on second die) = p*q + q*p = 2p*q

For (2,5): P(2 on first die) * P(5 on second die) + P(5 on first die) * P(2 on second die). Since 2 and 5 each have probability 1/6, so this is (1/6)*(1/6) + (1/6)*(1/6) = 2*(1/36) = 1/18

Similarly for (3,4): same as (2,5), so another 1/18.

Therefore, total probability of sum 7 is 2pq + 1/18 + 1/18 = 2pq + 1/9.

But according to the problem, this probability is 47/288. So:

2pq + 1/9 = 47/288

Let me compute 1/9 as 32/288. Therefore:

2pq + 32/288 = 47/288 => 2pq = 47/288 - 32/288 = 15/288 = 5/96 => pq = 5/192

But earlier, we had p + q = 1/3.

So now, we have:

p + q = 1/3

pq = 5/192

Therefore, we can set up a quadratic equation. Let me denote p and q as roots of x² - (p + q)x + pq = 0 => x² - (1/3)x + 5/192 = 0.

Multiply through by 192 to eliminate denominators:

192x² - 64x + 5 = 0

Let me check that:

Original equation: x² - (1/3)x + 5/192 = 0

Multiply by 192:

192x² - 64x + 5 = 0. Yes.

Now, solving this quadratic equation for x:

Discriminant D = b² - 4ac = (-64)² - 4*192*5 = 4096 - 3840 = 256

Square root of D is 16.

Solutions:

x = [64 ± 16]/(2*192) = [64 ± 16]/384

So,

First solution: (64 + 16)/384 = 80/384 = 5/24 ≈ 0.2083

Second solution: (64 - 16)/384 = 48/384 = 1/8 = 0.125

Therefore, the solutions are p = 5/24 and q = 1/8, or p = 1/8 and q = 5/24.

But remember, p is the probability of face F, which is greater than 1/6 ≈ 0.1667. Let's check:

5/24 ≈ 0.2083 > 1/6 (≈ 0.1667), so that works.

1/8 = 0.125 < 1/6 ≈ 0.1667, so that's q. Therefore, since p is the probability of F, which is greater than 1/6, p must be 5/24. Therefore, the answer is 5/24, so m = 5 and n = 24, m + n = 29.

Wait, but hold on. Let me check again. Wait, if F is 1, then p = probability of 1 is 5/24, which is greater than 1/6, and q = probability of 6 is 1/8, which is less than 1/6, which fits. But what if F was another face?

Wait, for example, suppose that F is 2. Then, the opposite face is 5, so p would be the probability of 2, which is greater than 1/6, and q is probability of 5, which is less than 1/6. Then, when computing the probability of sum of 7, we would have:

For the pair (2,5): same as before. Wait, let me recalculate the total probability of sum 7 in this case.

But if F is 2, then:

The die has:

Probability of 2: p

Probability of 5: q

Other faces (1, 3, 4, 6) have probability 1/6 each.

Therefore, when computing the sum of 7, the pairs are (1,6), (2,5), (3,4). Therefore, the same as before. For each of these pairs:

(1,6): same as before, each with probability 1/6. So the contribution is 2*(1/6 * 1/6) = 2*(1/36) = 1/18

Similarly for (3,4): same as above, 1/18

For (2,5): probability is p*q + q*p = 2pq.

Therefore, same as before. Therefore, regardless of which pair F is in, the total probability is 2pq + 1/9. Hence, same equation. Therefore, regardless of which face F is, the result is same. Therefore, p is 5/24. Therefore, answer is 5/24, m + n = 29.

Wait, but before I conclude, let me check whether there could be any other possibilities. For example, maybe the die's probabilities for the other faces are not all 1/6?

Wait, no. The problem states: "the probability of obtaining each of the other faces is 1/6". So, if F is one face, and its opposite is another face, then the other four faces (the ones not F nor opposite(F)) have probability 1/6 each. So regardless of which pair F is in, the calculation is same. Hence, the same equation.

But let me check the arithmetic again. Let me recast the equations.

Given that total probability is 1:

p + q + 4*(1/6) = 1 => p + q = 1 - 2/3 = 1/3. Correct.

Then, the probability of getting a sum of 7 is:

For the pair (F, opposite(F)): 2*p*q

For the other pairs (which are (a, b) where a and b are not F or its opposite, and each of those has probability 1/6. So for each of the other two pairs (since there are three pairs total: (F, opposite(F)), and the other two pairs), each of those pairs contributes 2*(1/6 * 1/6) = 2*(1/36) = 1/18 per pair. Since there are two such pairs, total contribution is 2*(1/18) = 1/9.

Hence total probability is 2pq + 1/9 = 47/288.

Then solving:

2pq = 47/288 - 1/9 = 47/288 - 32/288 = 15/288 = 5/96. Hence pq = 5/192. Then, solving p + q = 1/3 and pq = 5/192. So quadratic equation x² - (1/3)x + 5/192 = 0. Multiply by 192: 192x² - 64x + 5 = 0. Discriminant: 64² - 4*192*5 = 4096 - 3840 = 256. sqrt(256) = 16. So solutions: [64 ±16]/(2*192). So (64 + 16)/384 = 80/384 = 5/24, and (64 -16)/384 = 48/384 = 1/8. So p is 5/24 (since p > 1/6) and q is 1/8.

Therefore, the probability of F is 5/24. 5 and 24 are coprime? 5 is prime, 24 is 2^3*3. 5 doesn't divide 24. So yes, reduced fraction. Therefore, m + n = 5 + 24 = 29.

Wait, but let me check again the calculation of 47/288 - 1/9. Let me verify:

Convert 1/9 to 32/288, because 1/9 = 32/288? Wait:

Wait, 1/9 = 32/288? Let me check. 288 divided by 9 is 32. Yes, because 9*32 = 288. So yes, 1/9 = 32/288. Then 47/288 - 32/288 = 15/288. Simplify: divide numerator and denominator by 3: 5/96. Yes, correct. So pq = 5/96? Wait, no:

Wait, 2pq = 15/288 => pq = 15/576 = 5/192? Wait, 15 divided by 2 is 7.5? Wait, wait:

Wait, 2pq = 15/288 => pq = (15/288)/2 = 15/576 = 5/192. Yes, correct.

Therefore, solving quadratic equation is correct. Therefore, answer 5/24. So m + n = 29. Therefore, I think the answer is 29.

But just to be thorough, let me check if there's another way that the probability of getting sum 7 could be calculated, perhaps I missed some combinations?

Wait, for example, suppose that the face F is 1, and its opposite is 6. Suppose that when rolling two dice, there are other ways to get a sum of 7. Wait, no. The sum of 7 can only be achieved by the pairs (1,6), (2,5), (3,4). So if you roll two dice, the only way to get 7 is to have one die show a number from one pair and the other die show the opposite. Therefore, the calculation is correct.

Alternatively, let's think about all possible combinations:

Total number of possible outcomes? Well, since the die is unfair, the probability isn't uniform, but the probability of each outcome is the product of the individual probabilities. So, the total probability of getting sum 7 is as above.

Alternatively, suppose we think of the probability as follows:

Each die has probabilities:

For face F: p

For opposite face of F: q

For other four faces: 1/6 each.

Therefore, for two dice, the probability of (F, opposite(F)) is p*q, and (opposite(F), F) is q*p, so total 2pq. For the pairs (a, b) where a and b are not F or opposite(F), each pair contributes 2*(1/6 * 1/6) = 1/18. Since there are two such pairs, total 2*(1/18) = 1/9. Therefore, total probability 2pq + 1/9. So that's correct.

Therefore, solving gives p = 5/24. Hence, answer 5 + 24 = 29.

But just to check, let me compute the probability with p = 5/24 and q = 1/8.

Compute 2pq + 1/9:

2*(5/24)*(1/8) + 1/9 = 2*(5/192) + 1/9 = 10/192 + 1/9 = 5/96 + 1/9.

Convert to common denominator, which is 288:

5/96 = 15/288, 1/9 = 32/288. Total: 15 + 32 = 47/288. Which matches the given probability. Perfect.

Therefore, the answer is indeed 5/24. Therefore, m + n = 5 + 24 = 29.

I think that's solid. So I think the answer is 29.

**Final Answer**
\boxed{29}

To solve the problem, we consider the behavior of a specific unfair six-sided die. The die has the following characteristics:

- Each face is labeled with a number from 1 to 6.
- Opposite faces sum to 7. Thus, the pairs are (1,6), (2,5), and (3,4).
- A face $ F $ has a probability $ p $, which is **greater than** $ \frac{1}{6} $.
- The face opposite to $ F $ has probability $ q $, which is **less than** $ \frac{1}{6} $.
- The four other faces each have probability $ \frac{1}{6} $.
- The total sum of probabilities is 1:
  $$
  p + q + 4 \cdot \frac{1}{6} = 1 \Rightarrow p + q = \frac{1}{3}
  $$

We are given that when rolling two such dice, the probability of obtaining a sum of 7 is $ \frac{47}{288} $. We aim to find the probability $ p $ of face $ F $, and then compute $ m + n $ where $ p = \frac{m}{n} $ in simplest form.

### Step 1: Express Probability of Sum = 7

To compute the probability of getting a sum of 7 with two dice, we consider all pairs of numbers $ (i, j) $ such that $ i + j = 7 $. These are the pairs:

- $ (1,6) $
- $ (2,5) $
- $ (3,4) $

Each of these contributes to the total sum of 7 in two ways for distinct $ i $ and $ j $:
- $ i $ on first die, $ j $ on second die
- $ j $ on first die, $ i $ on second die

So, the probability of each pair (like $ (1,6) $) is:
$$
P(i=j) + P(j=i) = 2 \cdot P(i) \cdot P(j)
$$

Now, let’s examine how the pairs contribute to the total probability of getting a sum of 7.

- The pair $ (F, \text{opposite}(F)) $: has probability $ 2pq $
- The other two pairs (e.g., if $ F = 1 $, then $ (2,5) $ and $ (3,4) $), each contribute $ 2 \cdot \frac{1}{6} \cdot \frac{1}{6} = \frac{2}{36} = \frac{1}{18} $

So the total probability of getting a sum of 7 is:
$$
P(\text{sum} = 7) = 2pq + \frac{1}{18} + \frac{1}{18} = 2pq + \frac{1}{9}
$$
This expression is universal regardless of which face $ F $ is chosen, due to the symmetry of the die's probability distribution.

We are told that:
$$
2pq + \frac{1}{9} = \frac{47}{288}
$$

---

### Step 2: Solve for $ p $ and $ q $

First, solve for $ 2pq $:
$$
2pq = \frac{47}{288} - \frac{1}{9} = \frac{47}{288} - \frac{32}{288} = \frac{15}{288} = \frac{5}{96}
\Rightarrow pq = \frac{5}{192}
$$

We also know that:
$$
p + q = \frac{1}{3}
$$

We now solve the system:
$$
p + q = \frac{1}{3}, \quad pq = \frac{5}{192}
$$

These are the roots of the quadratic:
$$
x^2 - \left(\frac{1}{3}\right)x + \frac{5}{192} = 0
$$

Multiply through by 192 to eliminate denominators:
$$
192x^2 - 64x + 5 = 0
$$

Now find the roots using the quadratic formula:
$$
x = \frac{64 \pm \sqrt{(-64)^2 - 4(192)(5)}}{2(192)} = \frac{64 \pm \sqrt{4096 - 3840}}{384}
= \frac{64 \pm \sqrt{256}}{384}
= \frac{64 \pm 16}{384}
$$

Two roots:
$$
x_1 = \frac{80}{384} = \frac{5}{24}, \quad x_2 = \frac{48}{384} = \frac{1}{8}
$$

Now assign:
- Since $ p > \frac{1}{6} $, and $ \frac{5}{24} \approx 0.208 $, which is greater than $ \frac{1}{6} \approx 0.166 $, we assign $ p = \frac{5}{24} $
- Therefore, $ q = \frac{1}{8} $

---

### Step 3: Final Answer

Given that the probability of face $ F $ is $ p = \frac{5}{24} $, we express this as a reduced fraction $ m/n $, where $ m = 5 $ and $ n = 24 $. Since 5 and 24 are relatively prime, we find:
$$
m + n = 5 + 24 = \boxed{29}
$$

Solution:
Let $p(a,b)$ denote the probability of obtaining  $a$ on the first die and $b$ on the second.  Then the probability of obtaining a sum of 7 is $$p(1,6)+p(2,5)+p(3,4)+p(4,3)+p(5,2)+p(6,1).$$Let the probability of obtaining face $F$ be $(1/6)+x$.  Then the probability of obtaining the face opposite face $F$ is $(1/6)-x$. Therefore $$\begin{aligned}{{47}\over{288}}&=
4\left({1\over6}\right)^2+2\left({1\over6}+x\right)
\left({1\over6}-x\right)\cr&=
{4\over36}+2\left({1\over36}-x^2\right)\cr&=
{1\over6}-2x^2.\end{aligned}$$Then $2x^2=1/288$, and so $x=1/24$. The probability of obtaining face $F$ is therefore $(1/6)+(1/24)=5/24$, and $m+n=\boxed{29}$.
