Show answer & explanation
Correct answer: D
Solution: Count the total and favorable outcomes.
Total ordered outcomes when rolling two dice: 6 × 6 = 36.
Favorable ordered outcomes that sum to 11: (5,6) and (6,5). This gives 2 favorable outcomes.
Probability = favorable outcomes / total outcomes = 2/36 = 1/18.
