When is a set a superset? |
A superset is one that contains all the elements of a smaller set. For example, if B is a subset of A, then A is a superset of B; in other words, A is a superset of set B if every element in B is in A. Like a proper subset, there are also proper supersets (or a superset that is not the entire set).
