Prob(Sum is not divisible by 3) = 24/36 = 2/3
The probability of rolling a sum of 8 with two dice is 5 in 36 or about 0.1389. 2 and 6 3 and 5 4 and 4 5 and 3 6 and 2
The probability of rolling a 4 in a die is 1 in 6, or about 0.1667. The probability, then, of rolling a 4 in at least one of two dice rolls is twice that, or 2 in 6, or 0.3333. The probability of rolling a sum of 4 in two dice is 3 in 36, or 1 in 18, or about 0.05556.
I am not sure but I think 3/36
assuming a single six sided die the probability of rolling a three is 1/6
There are 36 permutations of rolling two standard dice. Of them, four (1+4, 2+3, 3+2, and 4+1) sum to five, and three (6+4, 5+5, and 4+6) sum to ten. The probability, then of rolling a multiple of five is 7 in 36, or about 0.1944.
It is 1/6.
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 17/18.
It is 3/4.
Prob(Sum is not divisible by 3) = 24/36 = 2/3
For standard dice, there are 36 outcomes for rolling 2 dice. There are 3 ways to roll a 4; 3,1 1,3 & 2,2. The probability of sum of 4 is then 3/36 or 1/12 or 0.0833.
The probability of rolling a sum of 5 with two dice is 4 in 36, or 1 in 9, or about 0.1111. 1 and 4 2 and 3 3 and 2 4 and 1
It is 2/36 = 1/18
The probability of rolling a sum of 8 with two dice is 5 in 36 or about 0.1389. 2 and 6 3 and 5 4 and 4 5 and 3 6 and 2
There are 3 ways to roll a sum of four, 5 ways to roll a sum of eight and 1 way to roll a sum of 12. That makes 9 out of 36, or 1/4.
3/11
