    Question

    Suppose it is known that a proportion of 0.002 of Dutch women have disease D. There is a test to detect this disease. That test is not always reliable: in 0.04 of the cases in which the affected person has the disease, the test gives the result of no disease. 0.96 of those affected are detected with a positive result. Further : 0.96 of those who do not have the disease get a negative (no disease) result. Marja is told that she has a positive test result.

    Set the events:

    Then what is the probability P(D and P)?


    1. TRUE: 0,0019
    2. FALSE: 0,0008
    3. FALSE: 0,0399
    4. FALSE: 0,9581
