C Correct answer
Explanation

Total outcomes for 3 dice = 6^3 = 216. Outcomes with no 2 = 5^3 = 125. Outcomes with at least one 2 = 216 - 125 = 91.

AI explanation

Calculate the total outcomes for three dice, which is 6 times 6 times 6, equaling 216. Find the outcomes where no die shows a 2 by calculating 5 times 5 times 5, which is 125. Subtract the outcomes without a 2 from the total outcomes to get the number of outcomes with at least one 2. Therefore, 216 minus 125 equals 91.
