A die is rolled twice. What is the probability sum is greater than 9?
- 1/4
- 1/5
- 1/6
- None of these
Explanation
When a die is rolled twice, total outcomes = 6 × 6 = 36
We need sum > 9, so sums 10, 11, 12
Sum 10: (4,6), (5,5), (6,4) → 3 ways
Sum 11: (5,6), (6,5) → 2 ways
Sum 12: (6,6) → 1 way
Total favorable outcomes = 3 + 2 + 1 = 6
Probability = favorable / total = 6/36 = 1/6.
