Formula to find number of proper subsets is = 2 n - 1. Substitute n = 5. = 2 5 - 1 = 32 - 1 = 31. So, the given set A has 31 proper subsets. Problem 2 : Let A = {a, e, i, o, u}. Find the number of

num = [5, 49, 10, 27] subsetnumber = 1 # Always includes itself subsetsin = set (num) subsetlength = len (subsetsin) for i in range (2, subsetlength): subsetnumber += subsetlength *

The number of proper subsets of a given sub-set is \(2^n-1\). Example: Determine the number of subsets and proper subsets for the set P = {7, 8, 9}. Solution: $$P = {7, 8, 9}$$ So, the number
