Suppose, in a car shop, the number of cars sold by a salesman follows a probability distribution with an average number of 2 cars sold per week by that salesman. a) What is the probability that, at least 5 cars are sold in the next 4 weeks? b) Find the probability that in the next twelve weeks there are exactly 9 weeks in which more than 5 cars are sold. c) The shop owner decides that the salesman will receive a bonus if he sells more than 25 cars in the next 10 weeks. Use a suitable approximation to estimate the probability that the salesman will receive the bonus.
