Consider the chance experiment described in the previous exercise.

a. What is the estimated probability that a randomly selected customer downloads five or more songs?

b. What is the estimated probability that a randomly selected customer downloads one or two songs?

c. What is the estimated probability that a randomly selected customer downloads more than two songs? Show two different ways to compute this probability that use the probability rules of this section.

Previous exercise

The manager of an online music store has kept records of the number of songs downloaded in a single transaction by customers who make a purchase at the store. Consider the chance experiment of observing the number of songs downloaded by a randomly selected customer. The accompanying table gives six possible outcomes and the estimated probability of each of these outcomes.
