Based on fleet-wide averages, a CO believes that 1% of his/her sailors used illegal drugs in the past month. Suppose that a test detects such drug use as follows:(a)If someone has used illegal drugs in the past month, there is a 99% chance the test will correctly detect the drug use (i.e., a 1% false negative rate).(b) If someone has not used illegal drugs (in the last month), there is a 0.5% chance the test will falsely indicate drug use (i.e., a false positive).What is the chance that a positive drug test signals a drug user?
