Find the probability of at most one tail appearing on two tosses of a coin.

Answer 1

wouldn't it just be a 50/50 chance since there are only two sides to a coin

Answer 2

at most one tail = not two tails
P(2 tails)=1/2*1/2=1/4
P(not 2 tails)=1-P(2 tails)=1-1/4

Answer 3

The answer is correct .75. Thank You Very Much. I really appreciate it =)
