WebSolution: Let there be two sets A and B A is the set of letters in “ALLOY” B is the set of letters in “LOYAL” Hence, A = {A,L, O,Y} B = {L,O,Y,A} Therefore, in both sets, the elements are the same. So, A = B. Subsets: A set A is said to be a subset of set B if every element of A is also an element of B Symbolically, A ⊂ B if a ∈ A ⇒ a ∈ B.
