Caden Adkins · Answer 1

1/2 is the probability of getting exactly one tail

Marcelo Guerrero · Answer 2

The event space of getting exactly one tail is {HT, TH}

The sample space is {HH, HT, TH, TT}

There are two ways to get exactly one tail, out of 4 total possible outcomes.

So 2/4 = 1/2 is the answer
