Question

What is the intersection of the sets A = {2, 3, 5, 7, 11} and B = {5, 11, 13, 15, 17}?

Answer 1

The intersection of sets is composed of the common elements.

The given sets have two common elements: 2 and 5.

{2;3;5;7}∩{2;5;11;13}={2;5}

Answer 2

A ∩ B = {5, 11}

Explanation:

Hello, the intersection of two sets A and B (A B), is the set that contains all elements of A that also belong to B , I mean , the common elements

Step 1

Let

A = {2, 3, 5, 7, 11}

B = {5, 11, 13, 15, 17}

you have to verify the common elements, first order the data from least to greatest to make it easier, here they are already sorted

A ∩ B = {5, 11}

Have a great day
