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.
It is 15/36.
Zero is the probability of rolling a sum of 15 on two fair dice; the maximum value is 12.
The probability is certain or 1. The max you can roll is 12 so it is certain the sum will be less than 13.
The probability of rolling 12 with 2 dice is 1 in 36. The probability of not rolling 12 with 2 dice is 35 in 36.

3/11
It is 15/36.
Zero is the probability of rolling a sum of 15 on two fair dice; the maximum value is 12.
The probability of rolling a sum of 11 with 2 dice is: P(11) = 1/18.For explanation see answer to question: "What is the probability of rolling 7 or 11 with 2 dice?".Read more: What_is_the_probability_of_rolling_7_or_11_with_2_dice
The probability is certain or 1. The max you can roll is 12 so it is certain the sum will be less than 13.
Assuming 2 dice, it is 0.
The probability of rolling 12 with 2 dice is 1 in 36. The probability of not rolling 12 with 2 dice is 35 in 36.
5 in 36
There are 36 permutations of two dice. Of these, 6 have a sum less than five, 1+1, 1+2, 1+3, 2+1, 2+2, and 3+1. The probability, then, of rolling a sum less than five on two dice is 6 in 36, or 1 in 6, or about 0.1667.
The probability is 1.
The probability is 29/36.
