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. Suppose that the probability of an overnight delivery selection is 0.2, the probability of a second-day delivery selection is 0.1, and the probability of a standard-delivery selection is 0.4. Find the following probabilities. (a) Find the probability that a randomly selected online purchase selects delivery to the nearest store for customer pick-up. 3 (b) Find the probability that the customer selects a form of expedited delivery. .02
