D Correct answer
Explanation

Possible outcomes: HH, HT, TH, TT. Outcomes with at least one tail: HT, TH, TT (3 outcomes). Total outcomes: 4. Probability = 3/4.

AI explanation

When two coins are tossed simultaneously, the total possible outcomes form a sample space of four combinations: HH, HT, TH and TT. The favorable outcomes for getting at least one tail are HT, TH and TT. Using the classical probability formula, the probability is 3 favorable outcomes divided by 4 total outcomes, which equals 3/4.
