1. WHAT
please tell me the probability one with ABC AND THE VENN DIAGRAM ETC WAS THE LAST QUESTION?
2. (Original post by SAM*)
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)
