Question

If a set contain 4 elements, then the total number of non- improper subsets of the is?​

Answer 1

Answer:

The number of sets of a set containing n-elements =2^n .

A proper subset of a set is the set whose elements are in the given set, but it is not equal to the set.

Let S be a subset of A, S is called Proper subset if and only if it is a subset of A, and S ≠ A .

So, The number of proper subsets of a set containing n-elements is  

As, The number of subsets contains a improper subset that is the set itself, so 1 is subtracted from number of total subsets to get number of proper subsets.
