Translate the following inference to logic notation: For all x, if x were a taxi driver, then x is playing squash. For all x, x is a musician if and only if x is an electrician. For all x, if x plays squash, then x is a musician. Therefore for all x, if x were a taxi driver, then x is an electrician.
forall x: P(x) -> Q(x). forall x: R(x) <-> S(x). forall x: Q(x) -> R(x). Therefore forall x: P(x) -> S(x).
