Consider the statement: “My brother is left-handed, but if the key is not missing, then my brother is not left-handed; therefore, the key is missing." a. Assign letters to the basic propositions and write each hypothesis and the conclusion as an implication. b. Prove the correctness of your answer to item a. by using the logical equivalencies and/or rules of inferences tables from your text which are available below.
