    so there may be a (B n C) intersection or may not be, how do u know whether they touch or not then?

    !!I HATE PROBABILITY!!
    A and B are mutually exclusive so they DO NOT TOUCH
    A and C are Independent so they do touch as unless P(C) = 0 P(A n C) = P(A) x P(C).
    B and C will most likely have a value for P(B n C) as the question does not gove anything to indicate that they will not. See attachment for how I drew ven diagram (Basically a bit like the micky mouse face logo for disney, with A and B as the ears)
