B Correct answer
Explanation

Total outcomes = 36. Sum of 11 can be (5,6) or (6,5). Probability = 2/36 = 1/18.

AI explanation

When two dice are rolled, the total number of possible outcomes in the sample space is 6 multiplied by 6, which equals 36. To achieve a sum of 11, the only favorable outcomes are rolling a 5 and a 6, or rolling a 6 and a 5. The probability is the ratio of favorable outcomes to total outcomes, so 2 divided by 36, which simplifies to 1/18.
