2. Determine if the following argument is valid or not. Premises: (1) If the engine works, then the control light is on, provided that the battery is not dead. (2) If the battery is dead, then the engine does not work. (3) If the control light is on, then the engine works. Conclusion: If the battery is not dead, then the engine works and the control light is on. If the argument is valid, then provide a deductive proof. If...

QUESTION 3 Symbolize the following argument using the variables p, q, and r. Then construct a complete truth table to show whether or not the argument is valid. Use 1 for T(true) and 0 for F(false). Valid or Invalid? Why? Prove. Explain what your truth table shows. 10 points Total: 3 points for correct symbolic form, 4 points for valid/invalid and reason, 3 points for correct truth table. If Max studies hard, then Max gets an 'A' or Max gets...
Instructions: For each of the following argument forms, complete a proof of validity, by natural deduction, USING ALL 19 RULES OF INFERENCE. Please note that some of the proofs may allow for alternative sequences of steps. Other than that, there is only one proof possible for each argument form. f a proof is without error, then answer CORRECT, on the CANVAS TEST 4/FINAL page. If there is any error in a proof, then answer THE LINE ON WHICH THE ERROR...
