Question: The probability of an adverse reaction to a flu shot is 0.08. Let r be the number of people suffering a reaction from a flu shot that has been given to a group of 4 people.

a. Find P(r) for r = 0, 1, 2, 3, and 4.
b. What is the expected number of people that will have an adverse reaction to the shot?
c. Compute the standard deviation of the probability distribution.
d. Find P(1 or less have a reaction).
e. Find P(at least 1 person has a reaction).
