It is 1: if you roll the die often enough.
On a single roll of a fair die, the probability is 1/6.
the probability is 5/6
The probability of rolling the same number on five dice is (1/6)4, or about 0.0007716.
5 in 36
The probability of rolling at least one '1' with six dice is 66.5% [1-(5/6)^6]*100%
5/216
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 is 29/36.
