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.

The probability of rolling a sum of 8 is approx a 14% chance. There are 36 possibilities when rolling 2 die. There are 5 possibilities of rolling a sum of 8. → Probability = 5/36 = 5/36 x 100% ≈ 14%.
