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. For example, if A={1,3,5} then B={1,5} is a proper subset of A.
Is a proper subset of symbol?

What is subset formula?
If “n” is the number of elements of a given set, then the formulas to calculate the number of subsets and a proper subset is given by: Number of subsets = 2 n . Number of proper subsets = 2 n – 1 .
Can a proper subset be empty?
The empty set is not a proper subset of the empty set. It is still a subset. A set A is a proper subset of another B set if and only if all elements of A are contained within B, and B has at least one element that is not contained in A. The ampty set is a proper subset of all sets except itself.
Is null a subset of any set?
If A is the empty set then A has no elements and so all of its elements (there are none) belong to B no matter what set B we are dealing with. That is, the empty set is a subset of every set .
