Use a truth table to determine whether each statement is a tautology, a selfcontradiction, or neither.(a) (q −→ p) −→ (p ∨ ¬q)(b) (p ∧ q) ∧ (¬p ∨ ¬q)(c) ¬(p ∨ q) ←→ (¬p ∧ ¬q)(d) (¬q −→ p) ∨ ¬q
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
Determine whether the following statements are logically equivalent. Wherever possible, try to do so without using a truth table. d. P ^ (Q v (-Q)) and (¬P) ⇒ (Q ^ (¬Q)). e. (PQ) v R and P⇒ (Q v R). f. (P v Q) ⇒ Rand (P ⇒ R) v (Q ⇒ R)

EXERCISE 1.11.1: Valid and invalid arguments expressed in logical notation. Indicate whether the argument is valid or invalid. For valid arguments, prove that the argument is valid using a truth table. For invalid arguments, give truth values for the variables showing that the argument is not valid. (h) (1) q→p -q Ap -(p→q) 9 p -q -(p→q) Р q→P q→P P :-(p→q)
Are the following propositions logically equivalent? pq and (p→g) ^ (q→p) Show your proof using truth tables and by a series of logical equivalences. A True (B) False
Suppose ¬[(p → q) → (q → p)] is false. Can p→q have both possible truth values? Explain.
