In a Two-penny toss game,what is the probabilityof getting both heads?

Answer 1

Well, you should find all the possible outcomes first (the sample space).
H = heads T = tails
1.) H, T
2.) H, H *** This is the favorable outcome, two heads in a row.
3.) T, H
4.) T, T

The favorable outcome is 1/4 of the possible outcomes. Now we find the percent:
1 ÷ 4 = .25
.25 × 100 = 25%

So, the probability is 25%.
