How to Calculate Conditional Probability
Formula
P(A Conditional probability measures how the probability of event A changes when we know event B has occurred. The vertical bar "B) = P(A and B) / P(B)
Example Calculation
P(A and B) = 0.12 and P(B) = 0.4. Find P(A|B).
- 01P(A|B) = P(A and B) / P(B)
- 02P(A|B) = 0.12 / 0.4
- 03P(A|B) = 0.3
- 04As a percentage: 30%
