The conditional probability formula is:

P(E∣F)=P(E∩F)P(F) P(E|F) = \frac{P(E \cap F)}{P(F)}

Where

  • P(E∣F)\small P(E|F) is the probability of event EE given event FF,
  • P(E∩F)\small P(E \cap F) (the intersection of the two events) is the probability of both events EE and FF occurring, and
  • P(F)\small P(F) is the probability of event FF.
