# Find A ∩ B, if A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}.

**Solution:**

**In mathematics, a set is a well-defined collection of objects. **

**Sets are named and represented using a capital letter.**

**In the set theory, the elements that a set comprises can be any kind of thing: people, letters of the alphabet, numbers, shapes, variables, etc**

Given:

Sets are** **A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}

A ∩ B is the intersection of set a and b.

Elements present in A = {4, 7, 10, 13, 17}

Elements present in B = {3, 5, 7, 9}

Elements present in both A and B = A ∩ B

A ∩ B = {7}

Therefore,

**A ∩ B = {7}.**

## Find A ∩ B, if A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}.

**Summary:**

If A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}, then A ∩ B = {7}.
