The union of sets A and B, denoted as A U B, includes all the unique elements from both sets. To find the number of elements in A U B, we need to count all the distinct elements present in both sets.
Set A = {1, 2, 3, 4, 5, 6}
Set B = {2, 3, 4, 5, 6, 7, 8}
By combining the elements from both sets and removing duplicates, we obtain:
A U B = {1, 2, 3, 4, 5, 6, 7, 8}
The number of elements in A U B is 8.
