B Correct answer
Explanation

There are 6 * 6 * 6 = 216 total outcomes. The favorable outcomes are (1,1,1), (2,2,2), (3,3,3), (4,4,4), (5,5,5), and (6,6,6), which is 6 outcomes. The probability is 6/216 = 1/36.

AI explanation

By the classical definition of probability, the sample space for rolling three dice contains 6 times 6 times 6, or 216 total outcomes. The favorable outcomes for getting the same number on all three dice are (1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5), and (6, 6, 6). The probability is the 6 favorable outcomes divided by 216, which simplifies to 1/36.
