Probability Basicshard
0:00.0
In a high-security facility, a theft is committed by exactly one of three employees. A security screening test is 80% accurate (meaning it correctly identifies a guilty person as positive with probability 0.8, and an innocent person as negative with probability 0.8). If a randomly selected employee tests positive, what is the probability that this employee is actually guilty?
