Philosophy 3. Multiple-Line Truth Functions Compound statements in propositional logic are truth functional, which means that their truth values are determined by the truth values of their statement components. Because of this truth functionality, it is possible to compute the truth value of a compound proposition from a set of initial truth values for the simple statement components that make up the compound statement, combined with the truth table definitions of the five propositional operators. To compute the truth value...

Construct a truth table to determine whether the following expression is a tautology, contradiction, or a contingency. (r ʌ (p ® q)) ↔ (r ʌ ((r ® p) ® q)) Use the Laws of Logic to prove the following statement: r ʌ (p ® q) Û r ʌ ((r ® p) ® q) [Hint: Start from the RHS, and use substitution, De Morgan, distributive & idempotent] Based on (a) and/or (b), can the following statement be true? (p ® q)...

Block copy, and paste, the argument into the window below. Use the short method or a truth table, and write if the argument is valid or invalid. If you use the short method, use a forward slash / for a check mark, or just write ok. If you use the truth table method, put an X after the line that proves that the argument is invalid. Block copy, and paste, the argument into the window below. Use the short method...
