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).
However, the conditional probability P (A | B 1) = 1, P (A | B 2) = 0.75, and P (A | B 3) = 0. On a tree diagram, branch probabilities are conditional on the event associated with the parent node.
