A survey of people on pizza preferences indicated that 55 percent preferred pepperoni only, 30 percent preferred mushroom only, and 15 percent preferred something other than pepperoni and mushroom. Suppose one person who was surveyed will be selected at random. Let represent the event that the selected person preferred pepperoni, and let represent the event that the selected person preferred mushroom. Are and mutually exclusive events for the people in this survey? Responses Yes, because the joint probability of and is greater than 0. Yes, because the joint probability of P and M is greater than 0. Yes, because the joint probability of and is greater than 1. Yes, because the joint probability of P and M is greater than 1. Yes, because the joint probability of and is equal to 0. Yes, because the joint probability of P and M is equal to 0. No, because the joint probability of and is equal to 1. No, because the joint probability of P and M is equal to 1. No, because the joint probability of and is equal to 0
