I remember there being AUB=5/8 and B=3/8,C=1/2 and C'(Intersect)B'=0.3


could you do me the favour to sketch it?

We can recreate the ven diagram if you remember the values they gave in the question

They don't add up to 1 because B and C intersect, I believe their intersction value was 7/20

I don't think this is right because I think B and C interset.. I'm not very sure but I'm sure that they didn't mention anywhere that B and C are also mutually exclusive.

Heh I'm not entirely sure that is correct but yes the probabilities inside the circles added up to less than 1.
