Best Answer: Hi kgwefkgwe. The number of subsets of n elemnets = 2^n. but this also includes a null set, because a null set is a subset of every set. So in our problem = 2^6 -1 = 63 subsets.
Cardinality of a set S, denoted by |S|, is the number of elements of the set. If a set has an infinite number of elements, its cardinality is â. |X| = |Y| represents two sets X and Y that have the same cardinality, if there exists a bijective function âfâ from X to Y.
