Discuss the below:
Q: Bill must sell three more cars this month to meet his quota. Tonight he has after-dinner appointments with five prospective customers, each of whom happens to be interested in a different car. If he has a %30 chance of success with each customer, what is the probability that he'll meet his quota by tomorrow morning? Suppose that three of Bill's customers were interested in the same car, and that they'll go elsewhere if it has already been sold. Would it be appropriate to use the binomial distribution under these conditions? Why or why not?
