## How to Calculate Conditional Probability ### Formula **P(A|B) = P(A and B) / P(B)** Conditional probability measures how the probability of event A changes when we know event B has occurred. The vertical bar "|" is read as "given". P(B) must be greater than zero.

P(A and B) = 0.12 and P(B) = 0.4. Find P(A|B).

  1. 01P(A|B) = P(A and B) / P(B)
  2. 02P(A|B) = 0.12 / 0.4
  3. 03P(A|B) = 0.3
