#cds-sampleTest
One in two hundred people in a population have a particular disease. A test is developed for the disease. The test gives a false positive $3\%$ of the time (i.e. reports that a person has the disease even when he/she does not), and a false ... disease even when he/she does). Rahul takes the test and the report comes positive. What is the probability that Rahul has the disease?
