In Exercises 43-50, use the standard forms of valid arguments to draw a valid conclusion from the given premises. If a person is a chemist, then that person has a college degree. My best friend does not have a college degree. Therefore, ...
Use Euler diagrams to determine whether each argument is valid or invalid. All physicists are scientists. All scientists attended college. Therefore, all physicists attended college.
Translate each argument into symbolic form. Then determine whether the argument is valid or invalid. It is the case that \(x<3\) or \(x>10\), but \(x \leq 10\), so \(x<3\).
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 I am tired or hungry, I cannot concentrate. I can concentrate. \(\therefore\) I am neither tired nor hungry.
Translate each argument into symbolic form. Then determine whether the argument is valid or invalid. "I do know that this pencil exists; but I could not know this if Hume's principles were true. Therefore, Hume's principles, one or both of them, are false."
