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.
Before we define a finite set, we need to establish what a set is. A set is a collection of elements or objects. Each element can be distinguished from other elements in the set. An example of a set would be all the prime numbers less than 20.
