Suppose that p is the probability that a randomly selected person is left-handed. The value 1 − p is the probability that the person is not left-handed. in a sample of 100 people, the function V p = 100 p 1 − p represents the variance of the number of left-handed people in a group of 100. a. What value of p maximizes the variance? b. What is the maximum variance?
