Denisse Hernandez · Accepted Answer

Final Answer : B, Explanation :  1. The probability of not rolling a 5 in one roll is 5/6.2. The probability of not rolling a 5 in six rolls is (5/6)^6.3. The probability of rolling at least one 5 in six rolls is 1 - (5/6)^6.4. Using a calculator, we get 1 - (5/6)^6 ≈ 0.665. Therefore, the answer is B.
