Once you have got to grips with these you will be able to arrange all sorts of groups and sets. Imagine there are two events.

Scroll down the page for more examples and solutions on how to shade venn diagrams to represent the required regions of two sets and three sets. Set a could represent a group of people who play the piano. The definition of conditional probability p a b read probability of a conditioned on b may be motivated by. A venn diagram also called primary diagram set diagram or logic diagram is a diagram that shows all possible logical relations between a finite collection of different sets these diagrams depict elements as points in the plane and sets as regions inside closed curves.

Conditional probability is based upon an event a given an event b has already happened. From the basic two circle venn diagram above it is easy to see that p aub p a p b p ab because the intersection ab is included in both a and b.

The following examples should help you understand the notation terminology and concepts relating venn diagrams and set notation. In order to use venn diagrams when talking about events we must first understand the term mutually exclusive. You write sets inside curly brackets like this.

This is written as p a b. Please choose the logical relationship from the table and the corresponding image will appear to explain the meaning. Conditional probability venn diagrams. The conditional probability is given by the sets and intersections of these sets.

Venn diagrams are widely used in the field of statistics computer science probability theory and set theory. Event a and event b. Let s say that our universe contains the numbers 1 2 3 and 4 so u 1 2 3 4 let a be the set containing the numbers 1 and 2. For example the items you wear is a set.
