Question: The probability that a randomly selected individual has a specified medical condition is 0.05. A screening test for this condition has sensitivity 0.95. That is, the probability that an affected individual tests positive is 0.95. The specificity of the procedure is 0.98. That is, the probability that an individual not affected tests negative is 0.98. What is the probability that the screening test will produce a true positive reading? That is, given that the results of the test are positive, what is the probability that the individual has the condition?
