Suppose that a drug test for an illegal drug is such that it is 98% accurate in the case of a user of that drug (e.g. it produces a positive result with probability 0.98 in the case that the tested individual uses the drug) and 90% accurate in the case of a non-user of the drug (e.g. it is negative with probability 0.90 in the case the person does not use the drug). Suppose it is known that 10% of the entire population uses this drug. (a) What is the probability of a false positive with this test (e.g. the probability of obtaining a positive drug test given that the person tested is a non-user)? (b) What is the probability of obtaining a false negative for this test (e.g. the probability that the test is negative, but the individual tested is a user)? (c) You test someone and the test is positive. What is the probability that the tested individual uses this illegal drug?
