The manager of a music store has kept records of the number of CDs bought in a single transaction by customers who make a purchase at the store. The accompanying table gives six possible outcomes and  the estimated probability associated with each of these outcomes for the chance experiment that consists of observing the number of CDs purchased by a randomly selected customer at the store.

a. What is the estimated probability that the next customer purchases three or fewer CDs?
b. What is the estimated probability that the next customer purchases at most three CDs? How does this compare to the probability computed in Part (a)?
c. What is the estimated probability that the next customer purchases five or more CDs?
d. What is the estimated probability that the next customer purchases one or two CDs?
e. What is the estimated probability that the next customer purchases more than two CDs? Show two different ways to compute this probability that use the probability rules of this section.
