Consider the type of clothes dryer (gas or electric) purchased by each of five different customers at a certain store. (a) If the probability that at most one of these purchases an electric dryer is 0.428, what is the probability that at least two purchase an electric dryer? (b) If P(all five purchase gas) = 0.114 and P(all five purchase electric) = 0.003, what is the probability that at least one of each type is purchased?
