Best Answer

There are 36 permutations of rolling two dice. Of these, there are five that add up to a sum of 8...

6+2

5+3

4+4

3+5

2+6

This translates to an event (or sample) space of {62, 53, 44, 35, 26}.

The probability, then, of rolling a sum of 8 on two dice is 5 in 36, or about 0.1389.

What is the probability of not rolling sum of 6 with two fair dice?

The probability of not rolling a sum of six with two fair dice is 1 minus the probability of rolling a sum of six. There are 36 permutations of rolling two dice. Of these, five sum to six, 1+5, 2+4, 3+3, 4+2, and 5+1. The probability, then of rolling a sum of six is 5 in 36. The probability, then of not rolling a sum of six is 31 in 36, or about 0.8611.
