Question

Many U.S. households still do not have Internet access. Suppose 20 out of 80 households in a small southern town do not have Internet access. A company that provides high-speed Internet has recently entered the market.

The aim is to build goodwill and, with a free laptop, tempt nonusers into getting Internet access.
a. What is the probability that six laptop recipients do not have Internet access?
b. What is the probability that at least five laptop recipients do not have Internet access?
c. What is the probability that two or fewer laptop recipients do not have Internet access?
