Translate the following inference to logic notation: There is at least one x for which if x works, then x is an artist. For all x, x will work or x is not an artist. For all x, x is an electrician if and only if x will work. For all x, x is not an electrician. Therefore there is at least one x for which x is not an artist.
exists x: P(x) -> Q(x). forall x: P(x) or ~Q(x). forall x: R(x) <-> P(x). forall x: ~R(x). Therefore exists x: ~Q(x).
