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 2 Determine whether the following argument is valid using the long or short truth-table method. Premise 1 If Angela is hungry, she eats pizza. Premise 2 Angela is not eating pizza. Therefore, Angela is not hungry. The above argument is a) valid b) invalid
QUESTION 3 Determine whether the following argument is valid using the long or short truth-table method. P1 If Mary is hungry, she eats pizza. P2 If Bill is thirsty, he drinks water. P3 Mary is not eating pizza OR Bill is not drinking water. Therefore, Bill is not thirsty. The above argument is a) valid b) invalid
