What is the probability of getting a sum of 6 when rolling two number cubes?

Rolling 2 dice together can produce total scores from 2 (a 1 and a 1) to 12 a (6 and a 6) but there not all equally probable. You would score 6 with 1 + 5 or 5 + 1 or 2 + 4 or 4 + 2 or 3 + 3.
Because there are 6 numbers on No. 1 dice and 6 numbers on No. 2 dice there are 6 x 6 = 36 ways of scoring.
From the above you can see that your 5 possibilities out of 36 means that the probability is 5/36 = 0.138888(recurring decimal) = 13.89% correct to 2 decimal places.

What is the probability of rolling the same number when three number cubes are rolled?
The first roll doesn't matter for probability, it just sets the number to be rolled by the other two. So: P(rolling the same number three times) = P(rolling a particular number)2 = (1/6)2 = 1/36
What is the probability of rolling divisors of 12 on both dice?
Of all the six numbers on a cube, only the '5' is not a factor of 12.Probability of rolling a factor of 12 on the first cube = 5/6 .Probability of rolling a factor of 12 on the second cube = 5/6 .Probability of rolling a factor of 12 on both cubes = (5/6 x 5/6 ) = 25/36 = 694/9 %.
What is the probability of rolling a sum of 8 on at least one of two rolls of a pair of number cubes?
The probability of rolling a sum of 8 on one roll of a pair of dice is 5/36.The probability of not rolling a sum of 8 on one roll of a pair of dice is 31/36.The probability of rolling a sum of 8 twice on two rolls of a pair of dice is(5/36)(5/36) = (5/36)2 .The probability of rolling first a sum of 8 and then rolling a sum that is not 8 on thesecond roll is (5/36)(31/36).The probability of rolling a sum that is not 8 on the first roll and rolling a sum of 8in the second roll is (31/36)(5/36).So The probability of rolling a sum of 8 at least one of two rolls of a pair of dice is(5/36)2 + (5/36)(31/38) + (31/36)(5/36) = 0.258487654... ≈ 25.8%.
What is the probability of rolling a sum of seven with two number cubes?
Number of possible outcomes of one cube = 6Number of possible outcomes of the other cube = 6Number of possible outcomes of two cubes = 6 x 6 = 36Number of ways to roll a sum of 7 with two cubes = 61 - 62 - 53 - 44 - 35 - 26 - 1Probability of rolling the sum of 7 = 6/36 = 1/6 = (16 and 2/3) percent
