Translate the following inference to logic notation: There is at least one x for which if x_5 were an electrician, then x_5 is an artist. For all x, x_5 is an electrician or x_5 is not a bartender. For all x, x_5 is not an artist. Therefore there is at least one x for which x_5 is not a bartender.
exists x: P(x) -> Q(x). forall x: P(x) or ~R(x). forall x: ~Q(x). Therefore exists x: ~R(x).
