Determine whether the following is a valid argument: p → r q → r ¬(p ∨ q) ∴ ¬r Hint: You may use rules of inference and truth tables to arrive at your solution.

Use truth tables to evaluate whether the following argument form is valid. The argument form being valid means that the conclusion is true whenever all the premises are true. p ∨ q ∨ r ∼ r ∼ q ∴ p Claim: This argument form is valid. True False
(i.) p ∨ q p ∨ r p ∴ q ∧ r (ii.) ∀x (P(x) ∨ Q(x)) ∀x (Q(x) → R(x)) ∃x P(x) ∴ ∃x R(x)
