Translate the following inference to logic notation: For all x, if y_3 were a musician, then y_3 is running. For all x, if y_3 goes running, then y_3 is a musician. For all x, y_3 is not a musician. Therefore for all x, y_3 will not go running.
forall x: P(x) -> Q(x). forall x: Q(x) -> P(x). forall x: ~P(x). Therefore forall x: ~Q(x).
