We can make a chart for all the sums:
2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
1 | 2 | 3 | 4 | 5 | 6 | 5 | 4 | 3 | 2 | 1 |
You can see that the \(9\) has \(4\) possible ways, and there are \(36\) total ways to get all the sums. Therefore, your probability would be \(\frac{4}{36} = \frac{1}{9}\).
