The literacy rate for a nation measures the proportion of people age 15 and over that can read and write. The literacy rate in Afghanistan is 23.1%. Suppose you choose 15 people in Afghanistan at random. Let X = the number of people who are literate. Find the probability that more than five people in the sample are literate. 0 None of the choices 0 0.7?54 The number of misprint on a page of the Magazines has a Poisson distribution with mean 1.2.
