5: Truth tables are used to establish the validity of complex sentences. Show and explain how they ed to decide if a sentence is valid, satisfiable, or unsatisfiable. Also, show how they can be used astrate the soundness of inference. Use the Unit Resolution rule as an example. Discuss the ty of propositional inference.
