If P = {X : X is a Factor of 12} and Q = {X: X is a Factor of 16}, Find : Q – P and N(Q – P).

If P = {x : x is a factor of 12} and Q = {x: x is a factor of 16}, find : Q – P and n(Q – P).

One Line Answer

Q – P and n (Q – P)

Elements of set P = {1, 2, 3, 4, 6, 12}

Elements of set Q = {1, 2, 4, 8, 16}

∴ Q – P = 8, 16

n (Q - P) = 2
