Question

Find A ∩ B if A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7}. {5} {1, 2, 3, 5, 7, 8, 11, 14}

Answer 1

A ∩ B = {5}.

Explanation:

Given : A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7}.

To find : Find A ∩ B

Solution : We have given

A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7}.

Intersection : the intersection A ∩ B of two sets A and B is the set that contains common element in both set.

So, common element in A and B is 5.

Then ,

A ∩ B = {5}

Therefore, A ∩ B = {5}.

Answer 2

A ∩ B = {5}

Explanation:

We are trying to find the intersection (what they both have in common)

A = {2, 5, 8, 11, 14}

B = {1, 3, 5, 7}

The only thing they both have in common is 5

A ∩ B = {5}
