Question

Let A = {10, 20, 30, 40, 50, 60} and B = {10, 40, 60}. What is A ∩ B?

{10, 40}
{40, 60}
{10, 40, 60}
{10, 20, 30, 40, 50, 60}

Answer 1

The A ∩ B is {10, 40 ,60} .

Explanation:

As given in the question

A = {10, 20, 30, 40, 50, 60}

B = {10, 40, 60}

The intersection A ∩ B of two sets A and B is represented the set that contains all elements of A that also belong to B .

Thus the A ∩ B becomes

A ∩ B = {10, 40 ,60}

Therefore the A ∩ B is {10, 40 ,60} .

Answer 2

this means common members {10,40,60}
