Answer:
P(at least one tail) = 7/8

If you flip a coin, you have two outcomes- heads or tails. So let's find all the outcomes for flipping three coins.
H = heads. T = Tails
HHH P(what you want) = number of times it happens
HHT Total number of outcomes.
HTH
HTT P(at least one tail) = 7
THH 8
THT
TTH
TTT
