A bookstore sells two types of books (fiction and nonfiction) in several formats (hardcover, paperback, digital, and audio). For the chance experiment that consists of observing the type and format of a single-book purchase, two of the eight possible outcomes are a hardcover fiction book and an audio nonfiction book.

a. There are eight outcomes in the sample space for this experiment. List these possible outcomes.

b. Do you think it is reasonable to think that the outcomes for this experiment would be equally likely? Explain.
