If you roll a fair die twice, what is the probability of getting a 4 on both rolls?

• A. 1/12
• B. 1/6
• C. 1/36
• D. 1/72

Answer: (C)

When two independent events happen, you multiply their probabilities. For a fair die, the chance to get a 4 on one roll is 1/6. Since the two rolls don’t affect each other, the chance of getting a 4 on both rolls is (1/6) × (1/6) = 1/36. So the probability is 1/36.
