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.) He is intelligent or an overachiever. He is not intelligent. \(\therefore\) He is an overachiever.
Use a truth table to determine whether the symbolic form of the argument is valid or invalid. $$ \begin{aligned} &p \rightarrow q \\ &\underline{q \rightarrow r} \\ &\therefore \sim p \rightarrow \sim r \end{aligned} $$
Determine whether each argument is valid or invalid. All \(A\) are \(B\), no \(C\) are \(B\), and all \(D\) are \(C\). Thus, no \(A\) are \(D\).
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 an argument is in the form of the fallacy of the inverse, then it is invalid. This argument is invalid. \(\therefore\) This argument is in the form of the fallacy of the inverse.
Use Euler diagrams to determine whether each argument is valid or invalid. All actors are artists. Sean Penn is an actor. Therefore, Sean Penn is an artist.
