Two fair 6-sided dice are rolled. What is the probability the sum rolled is 9?

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 \(\frac{4}{36} = \frac{1}{9}\).
