Question

what is the meaning of subset ,proper suber set ,super subset ? it's urgent ​

Answer 1

Step-by-step explanation:

• Subset - a set of which all the elements are contained in another set.
• proper superset of a set A is a superset of A that is not equal to A. In other words, if B is a proper superset of A, then all elements of A are in B but B contains at least one element that is not in A. For example, if A={1,3,5} then B={1,3,4,5} is a proper superset of A.
• In mathematics, a set A is a subset of a set B, or equivalently B is a superset of A, if A is "contained" inside B, that is, all elements of A are also elements of B. A and B may coincide. The relationship of one set being a subset of another is called inclusion or sometimes containment.
