I need help again.

Recently, I have come across to some of the probability terms. But I not sure how to derive from one to another one. Is there any good info. or website about the properties of probability?I have a derivation here, anyone know how to derive it.

Pr(A,B|C)=Pr(A|B)P(B|C)

thanks.

Re: I need help again.

Again, you are asking question out of context. If you need meaningful answer, you should give more precise question along with its necessary context.

Pr(A,B|C)=Pr(A|B,C)P(B|C)
and
Pr(A,B|C)=Pr(A|B)P(B|C) when (B,C)=B , or B is subset of C
