We say that A is a subset of B if every element of A is also an element of B.In other words, A consists of some (possibly all) of the elements of B but doesn't have any elements that B doesn't have. If A is a subset of B, we can also say that B is a superset of A.. Examples: The empty set ∅ is a subset of any … heart halo png
