A viral infection is spread by contact with an infected person. Suppose that an infected person has contact with 15 healthy people, let X denote the number of people (out of these 15) who are infected. By "infected" we mean that the person develops symptoms of the infection. Based on previous research, the infection rate is 25%. Which distribution would you use to model this event? O Binomial (25, 0.15) Binomial (15, 0.25) Normal (15, 0.25) Normal (0.25, 15) What is the probability 5 or fewer (of the 15) become infected? 0.8516 0.6243 3.75
