Let ( A = {1, 2, 3, 4} ) and ( B = {3, 4, 5, 6} ). Find the cardinality of ( A cup B ).

Question

Accepted Answer

Step:1 ：First, we find the union of sets A and B, which is ( A cup B = {1, 2, 3, 4, 5, 6} ).Step:2 ：Then, the cardinality of a set is the number of elements in the set. Here, the number of elements in ( A cup B ) is 6.
