1. Prove the validity or invalidity of the following two arguments using the truth table method.Either binks are not nugs or mimsies are borogroves. If procastination does not drink hemlockthen I am not superman. If mimsies are not borogroves then procastination does not drinkhemlock. Therefore, either I am not superman or binks are not nugs.2.If you plant tulips, then your garden blooms early. If you plant asters then your garden bloomslate. Therefore, if you either plant tulips of plant asters, then respectively, either your gardenblooms early or late.
