Consider the chance experiment described in the previous exercise.

a. For customers who purchase a single book, the estimated probabilities for the different possible outcomes are given in the cells of the accompanying table. What is the probability that a randomly selected single-book purchase will be for a book in print format (hardcover or paperback)?

b. Show two different ways to calculate the probability that a randomly selected single-book purchase will be for a book that is not in a print format.

c. Calculate the probability that a randomly selected single-book purchase will be for a work of fiction.
