SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question.

45) A new car dealer observes that the number X of warranty claims for repairs on each new car sold is Poisson distributed, with an average of six claims per car. Compute the probability that a new car sold by the dealer will have no more than three warranty claims.

46) In a certain office, the number of typewriters that break down during any given week is Poisson distributed with λ = 2. What is the probability that more than three typewriters break down during a week? Enter your answer in the form a ± (b/c)ed where (b/c) is reduced.

47) Suppose the number of cars passing through a toll booth in a 10 minute interval is a Poisson random variable. If the average number of cars is 23, give an expression for the probability that n cars pass through the booth. Is pn = ((23)n/n!)e-23 correct?
