For two events, A and B, P(A) =1/2, P(B) =1/3, and P(A B) =1/4. Find P(B | A).
The symbol where is shows a box here is an upsidedown U. Does anyone know what they're asking for here. I P(A upsidedown U B) the same as P(A and B). I'm not sure how to answer the question because I can't interpret the sybmols.
Also, what does P(B|A) stand for? I is this P(B or A). Any help would be appreciated.
