Three men flip coins to see who pays for coffee. if all three match (all heads or all tails), they flip again. otherwise, the "odd man" pays for coffee. a what is the probability that they will need to flip the coins more than once
Hello! Possible outcomes on flipping 3 coins = 27 Probability of flipping 3 heads or HHH = 1/27 Probability of flipping 3 tails or TTT = 1/27 . The outcome must be all head or tail so they will flip more than one. Probability(HHH or TTT) = P(HHH) + P(TTT) P(HHH or TTT) = 1/27 + 1/27 P(HHH or TTT) = 2/27 . The answer is 2/27. :)
