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.
The empty set is a subset of every set. Let's define subset. A set is a subset of another set if every element of the set is also an element of the other set. Set A is a subset of Set B if every element of A is also an element of B.
