Example 2 If P = { a, b, c} and Q = {r}, find the sets P Q and Q P. Are these two products equal? P = { a, b, c } and Q = {r} P Q = {a, b, c} {r} = {(a, r), (b , r), (c , r)} Q P = {r} {a, b , c} = {(r, a), (r, b), (r, c)} Here, P Q Q P Since the corresponding first and second elements are not equal, hence the two ordered pairs are not equal.
