A laboratory blood test is 98% effective in detecting a certain disease when it is in fact, present. However, the test also yields a false positive result for 1.5% of the healthy person tested (i.e. if a healthy person is tested, then, the test will imply he has the disease). If 0.8% of the population actually has the disease, what is the probability that a person has the disease given that his test result is positive?
