A 4-person grievance committee is to include employees in 2 departments, A and B, with 12 and 28 employees, respectively. If the 4 people are selected at random from the 40 employees, what is the probability of selecting 3 from A and 1 from B? Ten computer circuit boards, including 2 that are defective, are sent to an assembly plant. The plant will select 3 at random and will return the entire shipment if 1 or more in the sample are found to be defective. What is the probability that the shipment will be returned?
