Answer:
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.A subset is a set whose elements are all members of another set. The symbol "⊆" means "is a subset of". The symbol "⊂" means "is a proper subset of". ... Since all of the members of set A are members of set B, A is a subset of B.A Subset is a set which contains all the elements of another set. Consider two sets A and B, if every elements present in A are also present in B, then the set is a Subset . But, In two sets A and B, B is a proper subset of A, if all the elements of B are in A, but A cont ains at least one element that is not in B .
