Translate the following inference to logic notation: There is at least one x for which x_5 will take a plane. For all x, x_5 is an artist. For all x, x_5 is not an artist. Therefore there is at least one x for which x_5 will take a plane and x_5 is happy.
exists x: P(x). forall x: Q(x). forall x: ~Q(x). Therefore exists x: P(x) and R(x).
