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. In probability theory, conditional probability is a measure of the probability of an event occurring, given that another event (by assumption, presumption, assertion or evidence) has already occurred. This particular method relies on event B occurring with some sort of relationship with another event A. In this event, … See more Conditioning on an event Kolmogorov definition Given two events A and B from the sigma-field of a probability space, with the unconditional probability of B being greater than zero (i.e., P(B) … See more In statistical inference, the conditional probability is an update of the probability of an event based on new information.

WebIf A and B are two events in a sample space S, then the conditional probability of A given B is defined as P ( A B) = P ( A ∩ B) P ( B), when P ( B) > 0. Here is the intuition behind the formula. When we know that B has occurred, every outcome that is outside B should be discarded. Thus, our sample space is reduced to the set B , Figure 1.21.
