(a) A is the event of getting at least one head.

(b) B is the event of getting exactly one head

#### Solution

The sample space (S) is
S = {TT, HT,TH, HH}
n(s) = 4

a) Let A be the event of getting at least one head.
A = {HT, HH, TH}
n(A) = 3

b) Let B be the event of getting exactly one head.
B = {HT, TH}
n(B) = 2
