events A and B are such that p(A) = 1/2 p(A'|b) = 1/3 p(A B) = 3/5 determine P(B|A'). totally have no idea.. how can i define p(A B) = 3/5 btw?

I'd suggest you draw a Karnaugh table. From the given data: where: .... (1) .... (2) Substitute (2) into (1): . Update the Karnaugh table: Therefore . Update the Karnaugh table: Now it's easy to get .
that karnaugh table was great! i don't think it's in my syllabus though learnt a new thing, thanks a lot the question suggested venn diagram, but i sucked in that. can we 'possibly' just do it with general rules lol?
