Conditional Probability Formula Venn Diagram

In probability theory conditional probability is a measure of the probability of an event occurring given that another event has by assumption presumption assertion or evidence occurred.

Conditional probability formula venn diagram. The notation for conditional probability is p b a read as the probability of b given a. The simple conditional probability calculator helps to calculate the possible probability values of 3 sets venn diagram. Let us write the formula for conditional probability in the following format hspace 100pt p a cap b p a p b a p b p a b hspace 100pt 1 5 this format is particularly useful in situations when we know the conditional probability but we are interested in the probability of the intersection. This is written as p a b.

Conditional probability is based upon an event a given an event b has already happened. This lesson covers how to use venn diagrams to solve probability problems. The formula p a b p a b x p b is introduced through this method and referred to but not used as part of the calculations the idea is for pupils to understand where this comes from. It explains how to use the formula in solving example problems in addition to using.
