Translate the following inference to logic notation: For all x, x_3 will drink water. For all x, x_3 is a musician or x_3 will play tennis. There is at least one x for which if x_3 were a musician, then x_3 is not drinking water. Therefore there is at least one x for which x_3 will play tennis.
forall x: P(x). forall x: Q(x) or R(x). exists x: Q(x) -> ~P(x). Therefore exists x: R(x).
