# Introduction to Venn Diagrams¤

Sample spaces and events and the relationships between the two are often shown by means of a Venn Diagram. The sample space S is depicted by a rectangle, while the events are depicted as regions, often circles, within the rectangle.

This example shows a Venn diagram depicting the event E (the shaded area).

This Venn diagram shows the event defined by the union of events E and F, written (EF).
