Question

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

empty set

{5}
{1, 2, 3, 5, 7, 8, 11, 14}

Answer 1

We have the common elements from A and B: 5;
Then, A ∩ B = {5}.

Answer 2

A ∩ B={5}

Explanation:

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

To find out A ∩ B , we find the intersection of A and B

Intersection of A and B are the numbers that lies on both sets A and B

In set A and set B , common number is 5

5 lies in both A and B

A ∩ B={5}
