1. A sample of 1000 computer chip is randomly selected from an inventory to be shipped to a customer in Vancouver from Ottawa. The distribution follows a Poisson path. It is also known that the process that produced the parts generates 0.4 % defective parts. What is the approximate probability that the shipment contains two or three defective parts?
2. An employment agency claims that it finds jobs for 85% of the people who use its services. A newspaper reporter investigating the claims of the agency did a survey of 90 people who used the service. What is the approximate probability that fewer than 70 of these people found jobs through the agency?
