# Math Help - Bayes rule for P(A|B, C)

1. ## Bayes rule for P(A|B, C)

What is the Bayes formula for P(A|B,X) if X are some observations using which I want to model P(A|X) and P(B|X)

Is this correct?

P(A|B,C) = P(A|X) * P(B|A,X) / P(B|X)

P(A|B,C) = P(A|X) * P(B|A,X) / P(B|X)
Please explain what the notation $P(A|B,C)$ means?
Or at least, how is it read?
