Two dice are rolled The probability that their sum is at least 9 equals?

Outcomes from rolling two dice:

Total Probability

2 1/36

3 2/36

4 3/36

5 4/36

6 5/36

7 6/36

8 5/36

9 4/36

10 3/36

11 2/36

12 1/36

So, the probability of rolling 9 or greater is 4/36+3/36+2/36+1/36 = 10/36 ~= 0.278 = 27.8%
