If there are n elements in a set the number of proper subsets of that set are 2^{n}  1. Example: A = {a,b,c,d,e}, Find out the number of proper subsets. There are 5 elements in a set. The number of proper subsets for the set are 2^{n}  1 = 2^{5}  1 = 321 = 31 Solution: 31 Directions: Find out the number of proper subsets for the given set. Also write at least five examples of your own.
