Prove that each argument is valid by replacing each proposition in the hypotheses with a variable to obtain the form of the argument, and define all variables in your answer. Then use the rules of inference to prove that the form (~ the logical steps from hypotheses to conclusion) is valid. Hypotheses: a. If I drive on the freeway, I will see the fire. b. I will drive on the freeway or take surface streets (or both). c. I am not going to take surface streets. Conclusion: ∴ I will see the fire.
