Probability of rolling a 3 is 2/36 & the probability of rolling a 6 is 5/36; probability of rolling a 3 or 5 is 2/36 + 5/36 = 7/36.

a 2 out of 6 probability

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.

5 out of 6 or 83.333%

The probability of rolling a sum of 5 with two die is 4 over 36, or 2 over 18, or 1 over 9.

a 2 out of 6 probability

The probability of rolling at least one 2 when rolling a die 12 times is about 0.8878. Simply raise the probability of not rolling a 2 (5 in 6, or about 0.8333) to the 12th power, getting about 0.1122, and subtract from 1.

1 in 6 = rolling a 2 5 in 6 = not rolling a 2

The probability of rolling a sum of 5 with two die is 4 over 36, or 2 over 18, or 1 over 9.

The probability of not rolling a 6 is 5/6.

The probability of rolling a number less than 5; which is a 4, 3, 2, or 1 is 4/6 or 2/3. The probability of tossing a head is 1/2. So, the probability of a roll less than 5 and a head is 2/3*1/2 or 1/3 or 0.333. 4/12

It is 1/3.
