C Correct answer
Explanation

Total outcomes for 3 coins is 2^3 = 8. Outcomes with exactly 2 heads are (HHT, HTH, THH), which is 3 outcomes. Probability = 3/8.

AI explanation

When three fair coins are tossed, the total number of possible outcomes is 2 cubed, which is 8. The favorable outcomes of getting exactly two heads are HHT, HTH, and THH, totaling 3 ways. The probability is the number of favorable outcomes divided by the total outcomes, giving 3 / 8.
