Probability of a sum of 9: 25/216 = 11.6%
What is probability of getting a sum 9?
What is the probability of getting a sum 9 from two throws of a dice? Explanation: In two throws of a dice, n(S) = (6 x 6) = 36.
What is the probability of getting a sum 9 from thrown of a pair of dice?
Hence, the probability of obtaining a sum of 9 on a single toss of a pair of dice = 364=91.

What is the probability of getting at least one?
To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1. That is, P(at least one) = 1 – P(none).
What is the probability of getting a sum of 7 when two dice are thrown?
For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
