EXERCISE 1.11.1: Valid and invalid arguments expressed in logical notation. Indicate whether the argument is valid or invalid. For valid arguments, prove that the argument is valid using a truth table. For invalid arguments, give truth values for the variables showing that the argument is not valid.
