    Question

    In the population, 2 in 100 people suffer from the disease F. Researchers are designing a test that can detect the disease. But this test is not 100% foolproof. The probability of a negative result in the absence of the disease is 0.8 and a positive result in presence is 0.6. Suppose the events:Ê
    * A: someone who has disease F,‖ * B: the test with a positive result.  Then what is the probability that the person being tested has the disease F, given that there is a positive result?


    1. TRUE: 0,061
    2. FALSE: 0,120
    3. FALSE: 0,160
