1. Conditional probability

In probability theory, a conditional probability is the probability that an event will occur, when another event is known to occur or to have occurred. If the events are A and B respectively, this is said to be "the probability of A given B". It is commonly denoted by P, or sometimes PB. P may or may not be equal to P, the probability of A. If they are equal, A and B are said to be independent. For example, if a coin is flipped twice, "the outcome of the second flip" is independent of "the outcome of the first flip". In the Bayesian interpretation of probability, the conditioning event is interpreted as evidence for the conditioned event. That is, P is the probability of A before accounting for evidence E, and P is the probability of A having accounted for evidence E.
