Translate the following inference to logic notation: For all x, if x drinks water, then x is an electrician. For all x, if x were an electrician, then x is drinking water. For all x, if x were an electrician, then x is drinking water. Therefore for all x, if x were an electrician, then x is drinking water.
forall x: P(x) -> Q(x). forall x: Q(x) -> P(x). forall x: Q(x) -> P(x). Therefore forall x: Q(x) -> P(x).
