Translate the following inference to logic notation: For all x, x_6 is not a cashier. For all x, if x_6 were a musician, then x_6 is not playing tennis. For all x, x_6 will not listen to a song or x_6 will play tennis. For all x, x_6 will listen to a song or x_6 is a cashier. Therefore for all x, x_6 is not a musician.
forall x: ~P(x). forall x: Q(x) -> ~R(x). forall x: ~S(x) or R(x). forall x: S(x) or P(x). Therefore forall x: ~Q(x).
