I know that ##P(A,B) = P(A|B) \ P(B)##. But If i should like to define conditional probabilities for already-conditioned probabilities ie.
$$P(A,B|C)$$
how should I do it?
Writing something like ##P(A,B|C) = P(A|B|C) \ P(B|C)## seems nonsensical, and I've seen stuff that suggests ##P(A,B|C) = P(A|B,C)\ P(B|C)##, but I don't understand what is the right answer.
Assistance is greatly appreciated.
