B Correct answer
Explanation

Sample space for two tosses is {HH, HT, TH, TT}. Only one outcome is TT. Probability is 1/4.

AI explanation

When tossing a coin twice, the sample space consists of four equally likely outcomes: HH, HT, TH, and TT. The probability of an event is the number of favorable outcomes divided by the total number of outcomes. Since getting two consecutive tails is exactly one outcome out of the four, the probability is 1/4.
