1) Using truth table, prove the below given Propositional Logic sentence whether it is valid, contradicting or satisfiable. Write your answer whether it is valid, contradicting or satisfiable. Solution: ((((P \rightarrow Q) \wedge (P \rightarrow R)) \rightarrow Q) \rightarrow ((\neg P \rightarrow R) \wedge (P \rightarrow Q))) 1. Determine the validity of the propositional logic sentence: (P \wedge Q) \rightarrow (P \vee \neg Q) (P \wedge Q) \rightarrow (P \vee \neg Q) 2. Evaluate the satisfiability of the following propositional logic expression: (P \rightarrow Q) \vee (\neg P \wedge \neg Q) (P \rightarrow Q) \vee (\neg P \wedge \neg Q) 3. Prove the contradiction of the propositional logic statement: (P \rightarrow Q) \wedge (P \rightarrow \neg Q) (P \rightarrow Q) \wedge (P \rightarrow \neg Q) 4. Determine the validity of the compound proposition: (P \wedge Q) \rightarrow (\neg P \vee \neg Q) (P \wedge Q) \rightarrow (\neg P \vee \neg Q) 5. Investigate the satisfiability of the propositional logic formula: (P \wedge \neg Q) \vee (\neg P \wedge Q) (P \wedge \neg Q) \vee (\neg P \wedge Q)
