A test for a rare disease has been developed. It is not 100% accurate and works as follows.The disease (D) occures 1 in a 1000 in a population(i.e., P(D)= 0.001)Given that a person has the disease (D), the test will give a positive result (Y) with probability 0.95. That is P(Y|D)=0.95.Given that a person does not have the disease (D'), the test will give a positive result with probability 0.03.

If a randomly selected person is tested and the result is positive (Y),What is the probability that the prson has the disease (D)?
