The probability of a randomly selected person is suffering from
a certain disease DIS is 0.001. The test to detect DIS has a
correct detection rate of one, that is, for a person with DIS, the
test will always detect the disease. But for a person without DIS,
the test has probability 0.005 to give false detection of the
disease. Given that a person tests positive for DIS, what is the
probability that person actually has it?
