What is the probability that the sum of the two numbers will be 7?

The combinations that yield a sum of 7 are 1 + 6, 2 + 5, 3 + 4, 4 + 3, 5 + 2, and 6 + 1: 6 different combinations. Therefore, the probability of rolling a 7 is 6/36, or 1/6. To find the probability that this will happen twice in a row, multiply 1/6 by 1/6 to get 1/36. Answer: B.
