Question: Suppose a drug test is 99% sensitive and 99% specific. That is, the test will produce 99% true positive results for drug users and 99%

Suppose a drug test is 99% sensitive and 99% specific. That is, the test will produce 99% true positive results for drug users and 99% true negative results for non-drug users. Suppose that 0.5% of people are users of the drug. If a randomly selected individual tests positive, what is the probability he or she is a user? NOTE: PROBABLITY IS A NUMBER BETWEEN O AND 1. fOR EXAMPLE, 10\% PROBABILITY IS 0.1. WRITE YOUR ANSWER USING 3 DECIMAL DIGITS. DO NOT ROUND UP OR DOWN
