Example 10 Let A = {a,e,i,o,u} and B = {a,b,c,d} Is A a subset of B ? No. (Why?). Is B a subset of A? No. (Why?) A = {a, e, i, o, u} B = {a, b, c, d} Is A ⊂ B ? For a set to be a subset of another set, it needs to have all elements present in the another set. In set A, {e, i, o, u} elements are present but these are not present in set B. Hence A ⊄ B. Is B ⊂ A ? For this condition to be true, are elements of sets B should be present in set A. In set B, {b, c, d} elements are present but these elements are not present in set A. Hence B ⊄ A.
