Just catching up on my Stats work...
On conditional probability now, just confused to what the difference is P(A' intersetionB) with P(A' unionB)
I'm just trying to visualise it ^^

The usual difference!

A' intersect B is everything in BOTH A' and B

A' union B is everything in A' or B or both

I believe means A' or B or A' and B, and means just A' and B.

Oh right, of course haha

So there is no difference between P(AUB) and P(BUA)? and P(AintersectionB) and P(BintersectionA)?
