What is the experimental probability that the sum is 8?

Answer: There are 36 outcomes in total. Five of them (2,6), (3,5), (4,4), (5,3) and (6,2) result in sum 8. So, assuming all outcomes are equiprobable, the answer is 5/36.

What is the probability of not getting a sum of 8 if a pair of dice is rolled?

The probability of any number occurring is 1 in 36 or 1 / 36. Then the probability an 8 will not occur is: 1 – 5 / 36 or 31 / 36.
