Question

Proper subset define?​

Answer 1

Explanation:

A proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in A but A contains at least one element that is not in B.

If A and B be two sets then A is called a proper subset of B if A not equal to phi and A not equal to B and B is called subsets of A
