EXAMPLE 3.7d A laboratory blood test is 99 percent effective in detecting a certain diseasewhen it is, in fact, present. However, the test also yields a "false positive" result for1 percent of the healthy persons tested. (That is, if a healthy person is tested, then, withprobability .01, the test result will imply he or she has the disease.) If .5 percent of thepopulation actually has the disease, what is the probability a person has the disease giventhat his test result is positive?
