Find A ∩ B if A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10, 12}?

Solution:

In set theory, for any two sets A and B, the intersection is defined as the set of all the elements in set A that are also present in set B.

We use the symbol '∩' that denotes 'intersection of'.

Intersection refers to the items which are common in both the sets

A = {3, 6, 9, 12}

B = {2, 4, 6, 8, 10, 12}

The items which are common in both the sets are

A ∩ B = {6, 12}

Therefore, A ∩ B is {6, 12}.

Find A ∩ B if A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10, 12}?

Summary:

If A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10, 12}, A ∩ B is {6, 12}. Intersection refers to the items which are common in both the sets
