Use Euler diagrams to determine whether each argument is valid or invalid. All insects have six legs. No spiders are insects. Therefore, no spiders have six legs.
Use Euler diagrams to determine whether each argument is valid or invalid. Some people enjoy reading. Some people enjoy TV. \(\overline{\text { Therefore, some people who enjoy reading enjoy TV. }}\)
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 all people obey the law, then no jails are needed. Some jails are needed. \(\therefore\) Some people do not obey the law.
Translate each argument into symbolic form. Then determine whether the argument is valid or invalid. If it was any of your business, I would have invited you. It is not, and so I did not.
Determine whether each argument is valid or invalid. No \(A\) are \(B\), some \(A\) are \(C\), and all \(C\) are \(D\). Thus, some \(D\) are \(C\).
