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

A test for detection of a particular disease is not fool proof. The test will correctly detect the disease 90% of the time, but will incorrectly detect the disease 1% of the time. For a large population of which an estimated 0.2% have the disease, a person is selected at random, given the test, and tod that he has the disease. What are the chances that the person actually have the disease?

In a city suppose 3% of the population is known to be affected by a particular disease. There is a test for the disease. Of there with the disease 98% test positive and of these without the disease 99.8% test positive. What would be the probability that an individual selected at random with a positive test result does not have the disease?
