A large department store offers online ordering. When a purchase is made online, the customer can select one of four different delivery options: expedited overnight delivery expedited second-business-day delivery, standard delivery, or delivery to the nearest store for customer pick-up. Consider the chance experiment that consists of observing the selected delivery option for a randomly selected online purchase What are the four simple events that make up the sample space for this experiment? expedited delivery, delivery to the nearest store for customer pick-upj (expedited delivery, standard delivery, delivery to the nearest store for customer pick-up (expedited overnight delivery, expedited second business day delivery, standard delivery, delivery to the nearest store for customer pick-up; (standard delivery, delivery to the nearest store for customer pick-up! (expedited second-business-day delivery, standard overnight delivery, delivery to the nearest store for customer pick-up Suppose that the probability of an overnight delivery selection is 0.2, the probability of a second-day delivery selection is 0.4, and the probability of a standard-delivery selection is 0.1 Find the probability that a randomly selected online purchase selects delivery to the nearest store for customer pick-up Find the probability that the customer selects a form of expedited delivery (iii) Find the probability that either standard delivery or delivery to the nearest store is selected.
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. fiction hardcover, fiction paperback, nonfiction digital, nonfiction audio, fiction hardcover, fiction paperback, nonfiction digital, nonfiction audio fiction hardcover, fiction paperback, fiction hardcover, fiction paperback, nonfiction digital, nonfiction audio, nonfiction digital, nonfiction audio fiction hardcover, fiction paperback, fiction digital, fiction audio, nonfiction hardcover, nonfiction paperback, nonfiction digital, nonfiction audio nonfiction hardcover, nonfiction paperback, nonfiction digital, nonfiction audio, nonfiction hardcover, nonfiction paperback nonfiction digital, nonfiction audio fiction audio, fiction paperback, fiction digital, fiction audio, nonfiction audio, nonfiction paperback, nonfiction digital nonfiction audio

(b) Do you think it is reasonable to think that the outcomes for this experiment would be equally likely? Explain. Yes, there are likely to be equal amounts of each type and format available. Yes, customers like each type and format equally. No. For example, a customer is more likely to buy a paperback than a hardcover book.

(c) For customers who purchase a single book, the estimated probabilities for the different possible outcomes are given in the cells of the accompanying table. Hardcover Paperback Digital Audio 0.15 Fiction Nonfiction 0.09 0.45 0.10 0.10 0.04 0.01 0.06 What is the probability that a randomly selected single-book purchase will be for a book in print format (hardcover or paperback)?

(d) Compute the probability that a randomly selected single- book purchase will be for a book that is not in a print format.

(e) Find the probability that a randomly selected single-book purchase will be for a work of fiction
