4.20 The multiplication rule for independent events. The probability that a randomly selected person prefers the vehicle color white is 0.24. Can you apply the multiplication rule for independent events in the situations described in parts (a) and (b)? If your answer is Yes, apply the rule.
(a) Two people are chosen at random from the population. What is the probability that both prefer white?
(b) Two people who are sisters are chosen. What is the probability that both prefer white?
(c) Write a short summary about the multiplication rule for independent events using your answers to parts (a) and (b) to illustrate the basic idea.
