Let P = probability = 60%, R1 = airline reservation of first member and R2 = airline reservation of second member.
Probability that first member made an airline reservation last year is .60, or P(R1) = .60
Probability second member made a reservation is .60, therefore P(R2) = .60
Since both members were selected randomly, we assume they are independent meaning one has no effect on the probability of the other,
P(R1 and R2) = P(R1)* P(R2) = (.60)*(.60) = .36
Therefore, the probability (P) that both made airline reservations last year is .36 or 36%.
