Question

Archie rolls two number cubes, each with sides numbered 1 through 6. He then finds the sum of the numbers on the top of the cubes.

Which two sums have the the same probability?

Answer 1

Your probability of getting a specific number on a die is 1/6. Since you have 2 dice the probability for each is 1/6. Multiply those together to find the probability that the numbers would be the same. So, 1/36 is the correct answer.
