Question: Suppose a certain drug test is 8 2 % sensitive , that is , the test will correctly identify a drug user as testing positive

Suppose a certain drug test is 82% sensitive, that is, the test will correctly identify a drug user as testing positive 82% of the time, and 84% specific, that is, the test will correctly identify a non-user as testing negative 84% of the time. What is the probability that, given a positive drug test, an employee is actually a drug user?
