Explanation

When two dice are rolled, there are 36 possible outcomes. The pairs that sum to 7 are (1,6), (2,5), (3,4), (4,3), (5,2), (6,1). There are 6 favorable outcomes. Probability = 6/36 = 1/6.

AI explanation

Apply the classical probability formula to find the chance of rolling a sum of 7 with two dice. The total number of outcomes in the sample space for two dice is 6 times 6, which equals 36. The favorable outcomes that add up to 7 are (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1), totaling exactly 6 combinations. Therefore, the probability is 6 divided by 36, which simplifies to 1/6. The answer is 1/6.
