conditional probability

English

Noun

conditional probability (countable and uncountable, plural conditional probabilities)

  1. The probability that an event will take place given the restrictive assumption that another event has taken place, or that a combination of other events has taken place. (Mathematically, the definition would be that the conditional probability of B given A is equal to the joint probability of A and B divided by the probability of A.)

Usage notes

  • The "probability of event B given event A" can be represented symbolically as P(B|A).
  • The "probability of event B given events A and C" can be represented symbolically as P(B|A,C).
