The cardinality of B is 4, since there are 4 elements in the set. The cardinality of A ⋃ B is 7, since A ⋃ B = {1, 2, 3, 4, 5, 6, 8}, which contains 7 elements.
If set A and set B have the same cardinality, then there is a one-to-one correspondence from set A to set B. For a finite set, the cardinality of the set is the number of elements in the set.
