WebConditional Probability Of Independent Events An independent event occurs when the outcome or condition of the previous (B) or subsequent (A) event has no bearing on either. Hence, the formula is: P (A B) = P (A) … WebThe formula for the Conditional Probability of an event can be derived from Multiplication Rule 2 as follows: Start with Multiplication Rule 2. Divide both sides of equation by P (A). Cancel P (A)s on right-hand side of equation. Commute the equation. We have derived the formula for conditional probability.
