This is part of HyperStat Online, a free online statistics book. ... Next section: Probability of A and B ; A conditional probability is the probability of an event given that another event has occurred. For example, what is the probability that the total of two dice will be greater than 8 given that the first die is a 6?

In general terms, the "conditional probability" P[A|B] is the probability that A occurs, given that B has occurred and is formally defined as: ... In other words, the conditional probability for our example is given by the following equation:

The conditional probability of an event B is the probability that the event will occur given the knowledge that an event A has already occurred. This probability is written P(B|A), notation for the probability of B given A.
