D Correct answer
Explanation

Sums > 9 are 10, 11, 12. Pairs: (4,6), (5,5), (6,4), (5,6), (6,5), (6,6). Total = 6 outcomes. Probability = 6/36 = 1/6.

AI explanation

When a pair of dice is thrown, the total number of outcomes is 36. A sum more than 9 means getting a sum of 10, 11, or 12, which corresponds to the favorable outcomes: (4, 6), (5, 5), (6, 4), (5, 6), (6, 5), and (6, 6). There are 6 favorable outcomes, so the probability is 6 divided by 36, which simplifies to 1/6. Since 1/6 is not listed among the choices, the result is None of the above.
