5 in 36
The probability of rolling the same number on five dice is (1/6)4, or about 0.0007716.
rolling 8 on a 6 sided dice? in a single roll? approximately 0. on a 12 sided dice? one in 12. two six sided dice? 5/36
5 out of 6
5/216
the probability is 5/6
11 = 6+5 is the only solution, so there are two combinations first dice : 6, second dice : 5 first dice : 5, second dice : 6
It is 30/36 = 5/6
There is always a 1 in 6 chance of rolling ANY number on a six-sided dice, as there are 6 numbers.
The probability of rolling at least one '1' with six dice is 66.5% [1-(5/6)^6]*100%
Since there are two permutations of two dice that sum to 11, (5-6) and (6-5), and since there are 36 permutations of rolling two dice, the probability of not rolling a sum of 11 is 34 in 36, or 17 in 18, or about 0.9444.
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.
