There are 4 events: 3 heads, 2 heads 1 tail, 1 head 2 tails, and 3 tails.

3 out of 8
The probability of tossing two heads in two coins is 0.25.
There are eight (8).
(0.5)n
Two coins tossed sample space is (H=Heads, T = Tails) as follows. HH, HT, TH, TT is the sample space.
Sample space for two coins tossed is: HH HT TH TT Therefore at most one head is HT TH TT or 3/4 or 0.75.
Assuming the variable of interest is the face on top: H (= heads) or T (= tails), then they are the four possible outcomes: HH, HT, TH and TT.
1/4 if they are tossed only once.
