Select term: Conditional Probability. The probability that event A occurs, given that event B has occurred, is called a conditional probability. The conditional probability of A, given B, is denoted by the symbol P(A|B).
Namely, P ( A | X ) = E ( Y | X ) if Y is the indicator of A. Therefore the conditional probability also depends on the partition Î±X generated by X rather than on X itself; P ( A | g(X) ) = P (A | X) = P (A | Î±), Î± = Î±X = Î±g(X).
