- Determine whether you can use a normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use a binomial distribution to find the indicated probabilities. Identify any unusual events. Explain. In a survey of U.S. adults, 19% said that they have participated in a clinical trial. You randomly select 220 U.S. adults. Find the probability that the number who have participated in a clinical trial is (a) no fewer than 34, (b) more than 44, and (c) between 39 and 49 inclusive.

A company is deciding where to place a restaurant that they are planning to build. They can build it on a center of a business district so they can charge higher but needs to compete with more restaurants nearby. They can also build it in front of a school where they have to charge less but they have less to compete with. The company analysed how those considerations will affect earning and they have presented their finding using a probability distribution.
