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

If the elements of set A and the elements of set B are the elements of a set, then it is called an intersection of sets and is denoted by the symbol ∩.

## Answer: The intersection set of set A= {4, 7, 10, 13, 17} and B = {3, 5, 7, 9} is A ∩ B = { 7}.

Let's find A ∩ B.

**Explanation:**

The intersection of set A and set B is defined as A ∩ B.

Elements of set A= {4, 7, 10, 13, 17}

Elements of set B = {3, 5, 7, 9}.

Elements of set A that are also Elements of set B = A ∩ B

⇒ A ∩ B = {7}

⇒ The intersection set A ∩ B consists of only one elements in common that is {7}
