The union of sets A and B, denoted as $A \cup B$, includes all elements that are in A, in B, or in both. For sets A = {1, 2, 8, 9} and B = {1, 3, 6, 7, 8}, the union is {1, 2, 3, 6, 7, 8, 9}, which contains 7 elements.

Let U = {0, 1, 2, 3, 4, 5, 6 ∣A∪B∣| A \cup B |∣A∪B∣

Let U = {0, 1, 2, 3, 4, 5, 6 $| A \cup B |$
