I. Cite two arguments you've heard of lately. Prove the argument if it's logically correct by: 1. Translating to symbolic logic. 2. Determining the rules of inference followed (if there's any). a. If the argument is logically incorrect, state the error made, or the changes that needs to be done. Example: Propositional Logic Symbolic Logic E → W Observed Rules of Inference 1. "If you send me an e-mail message, then I will finish writing the program." "If you do not send me an e-mail message, then I will go to sleep early." "I did not finish writing the program." Therefore, "I will go to sleep early." Modus Tollens ~E → S Modus Ponens

Thank you for your response, since it was not included in the response, is it possible to provide the logics you applied? Example for: p ∧ r , q ∧ r , p ∧ q, I know that it would be "If both A & B are true then A ∧ B is true otherwise false. I do not know how to denote statements with more than 2 variables. Therefore showing this will help me to understand. Thank you. Specifically, p ⊕ q ⊕ r p ∨ q ∨ r ¬ p ∧ r ∨ q ∧ r ∨ p ∧ q p ∨ q ∨ r ((p ∨ q ∨ r) ¬ (p ∧ r ∨ q ∧ r ∨ p ∧ q)) (p ⊕ q ⊕ r) ↔ ((p ∨ q ∨ r) ¬ (p ∧ r ∨ q ∧ r ∨ p ∧ q))

Find the truth table of the following logical expression: (¬pV¬q) → (p→¬q) · (Note: Type T for true or F for false) pa(pv¬q) → (p→¬q) TT TF FF
Determine whether the logical statement is a tautology, a contradiction or neither: (p→q) → (p v q). [Hint: Use a truth table with 4 rows; you need to check the last row; all T is a tautology: all F is a contradition; a mixture of T and F is neither.] Example statement: If adopting new software leads to savings, then we'll either adopt new software or save money. The parentheses fit in the statement like this: If (adopting new software leads to savings), then (we'll either adopt new software or save money). This interpretation gives adopting new software leads to savings = If we adopt new software, then we'll save money O a. Tautology O b. Neither Oc. Contradiction
