- 17 A man is restoring ten old cars, six of them manufactured in 1955 and four of them manufactured in 1962. When he tries to start them, on average the 1955 models will start 65% of the time and the 1962 models will start 80% of the time. Find, correct to four decimal places, the probability that at any time: a exactly three of the 1955 models and one of the 1962 models will start, b exactly four of the cars will start. (Hint: You will need to consider five cases.)2. Suppose you are at a birthday party with n other people.
