I'm trying to find the conditional probability of with 4 separate events. For example, I want to find:
P(A| B,C,D) and also all of the different variations of this i.e [P(B|A,C,D) etc.].
I've started out by finding the union of B, C, D (U) through p(B) + p(C) + p(D) - p(BC) - p(BD) - p(CD) + p(BC*D).
But I'm confused on what I should do next. Could someone please explain to me how I find:
P(A|U) = P(A) * P(U|A) / P(U) ==> I think I'm confused on the P(U|A) part.
