Transcribed Image Text:A laboratory blood test is 99% effective in detecting a
certain disease, when it is in fact present. However, the test
also yields a false positive result for 0.5% of the healthy
person tested (that is, if a healthy person is tested, then, with
probability 0.005, the test will imply he has the disease). If
0.1 percent of the population actually has the disease, what is
the probability that a person has the disease given that his test
result is positive?
