Use Euler diagrams to determine whether each argument is valid or invalid. All cowboys live on ranches. All cowherders live on ranches. Therefore, all cowboys are cowherders.
Use a truth table to determine whether the symbolic form of the argument is valid or invalid. \((p \rightarrow q) \wedge(q \rightarrow p)\) \(\therefore p \vee q\)
From Alice in Wonderland: "Alice noticed, with some surprise, that the pebbles were all turning into little cakes as they lay on the floor, and a bright idea came into her head. 'If I eat one of these cakes,' she thought, 'it's sure to make some change in my size; and as it can't possibly make me larger, it must make me smaller, I suppose." " Alice's argument: If I eat the cake, it will make me larger or smaller. It can't make me larger. \(\therefore\) If I eat the cake, it will make me smaller. Translate this argument into symbolic form and determine whether it is valid or invalid.
Translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if applicable, compare the argument's symbolic form to a standard valid or invalid form. (You can ignore differences in past, present, and future tense.) If we close the door, then there is less noise. There is less noise. \(\therefore\) We closed the door.
Use the standard forms of valid arguments to draw a valid conclusion from the given premises. If I vacation in Paris, I eat French pastries. If I eat French pastries, I gain weight. Therefore, ...
