7.2 Intersection of Sets

The intersection of sets A and B is the set of elements which are common to A and B.

Example:
If A = {1, 2, 3, 4} and B = {2, 4, 6}, then find A B.
Solution:
Given that, A = {1, 2, 3, 4} and B = {2, 4, 6}.
A B = {1, 2, 3, 4} {2, 4, 6}
The common elements in A and B are 2 and 4.
Therefore, A B = {2, 4}.


Directions: Choose the correct answer. Also write at least 5 examples of your own.
