Suppose that a laboratory test on a blood sample yields one of two results, positive or negative. It is found that 95% of the people with a particular disease produce a positive result. But, 2% of people without the disease will also produce a positive result (false positive). Suppose that 1% of the population actually has the disease. What is the probability that a person chosen at random from the population will not have the disease, given that the person’s blood yields a positive result?
