Conditional probability is the probability of some event A, given the occurrence of some other event B.

The probability of an event given (conditioned on) another event.

Suppose we are interested in the probability that some event A occurs, and we learn that the event B occurred. How should we update the probability of A to reflect this new knowledge? This is what the [..]

the likelihood that an occurrence will take place given that another occurrence is already understood as having happened.

Probability of occurrence given that a precursor even has occurred.

Probability of an event happening, given the occurrence of another event.

Probability of an event happening, given the occurrence of another event.

P(B|A), the probability of B given A.

The probability that one event is true, given that another event is true. See: Bayes’ theorem.

The probability of one event given some other event (e.g., if responses A and B occur equally often but A is followed by A 75 percent of the time and by B 25 percent of the time, the simple probabilit [..]

This is the probability of an event given (or conditional upon) the occurrence of another event, e.g. the probability of disease Y given exposure to factor X.

A probability dependent on, or influenced by, other events or circumstances. The probability that a woman is pregnant, if aged 35 to 39, is an example of a conditional probability. That is, the probab [..]

In many situations, once more information becomes available, we are able to revise our estimates for the probability of further outcomes or events happening. The probability of the A event given that [..]
