    Proabability With Test Questions

    I don't completely know how to set this problem up. The question is:
    An exam has only three true and false questions, the probability that you know the first question is 67%, the probability that you know the second question is 57% and the probability that you know the last question is 37%.
    What is the probability that you get all three correct?



    This is for a college class, but I think it be easier than I think it is.
