# Explain the intersection of two events, A and B.

Sets are very useful for representing one or more objects in the form of a Venn Diagram. They are also used to represent the common items in different sets and how they relate to each other. Two major concepts of sets are union and intersection. Let's discuss the concept of intersection on this page.

## Answer: Intersection of two events, A and B, is a set that contains all the elements of A that also belong to B and vice-versa.

Let's understand the statement in depth.

**Explanation:**

Let's take two sets, A and B.

Let's consider A = {1, 2, 3, 4, 5, 7} and B = {3, 7, 8, 9} as shown in the above picture. We can clearly see that {3, 7} are present in both sets and are marked in the region common to A and B. This region is called the intersection between A and B.
