Translate the following inference to logic notation: For all x, if y climbs a mountain, then y is taking a plane. For all x, y will climb a mountain. For all x, if y takes a plane, then y is cooking. Therefore for all x, y will cook or y is rich.
forall x: P(x) -> Q(x). forall x: P(x). forall x: Q(x) -> R(x). Therefore forall x: R(x) or S(x).
