The total number of outcomes is 4 (HH, HT, TH, TT).
The event of getting exactly one head can occur in 2 ways (HT, TH).
So, the probability of getting exactly one head is 2/4 = 0.5.
A fair coin is tossed two
times in succession. The set of equally likely outcomes is StartSet HH comma HT comma TH comma TT EndSet
.
