The employees of a firm that manufactures insulation are being tested for indications of asbestos in their lungs. The firm is requested to send two employees who have positive indications of asbestos to a medical center for further testing. If 40% of the employees have positive indications of asbestos in their lungs, find the probability that fifteen employees must be tested in order to find two positives. If each test costs $20, find the expected value in dollars and variance of the total cost of conducting the tests necessary to locate the two positives.
