If A and B are two sets, A È B contains elements which are either in A or in B or in both.

Example:
Find the union of A and B, if, A = {1, 3, 5, 7} and B = {2, 4, 6, 8}. Solution:
Given that, A = {1, 3, 5, 7} and B = {2, 4, 6, 8}.
A È B = {1, 3, 5, 7} È {2, 4, 6, 8}.
A È B = {1, 2, 3, 4, 5, 6, 7, 8}.
