Translate the following inference to logic notation: For all x, x_11 is a sailor or x_11 is not an artist. For all x, if x_11 were a sailor, then x_11 is playing tennis. For all x, x_11 is an artist or x_11 will not play tennis. Therefore for all x, if x_11 plays tennis, then x_11 is an artist.
forall x: P(x) or ~Q(x). forall x: P(x) -> R(x). forall x: Q(x) or ~R(x). Therefore forall x: R(x) -> Q(x).
