Explanation

The sample space for tossing a coin twice is {HH, HT, TH, TT}. There are 4 equally likely outcomes. Only one outcome is {TT}. Thus, the probability is 1/4.

AI explanation

Tossing a fair coin twice yields a total sample space of 4 outcomes: HH, HT, TH, and TT. The probability of getting two tails is calculated by dividing the 1 favorable outcome by the 4 total possible outcomes. The probability of getting two tails is 1/4.
