Proofs: Construct proofs to show that the following symbolic arguments are valid. Commas mark the breaks between premises, ‘∴’ precedes the conclusion. You may use any rule, but you must use CP (H∨E)→K ∴E→K
answer
Suppose A, B, and C are propositions. Using only the logical operations of conjunction, disjunction and negation, construct a proposition in Conjunctive Normal Form that is True if and only if exactly two of A, B, or C are True. Symbols you might find handy: A V

P and Q= statement. Use only one method to determine whether the compound statement provided is a tautology , controdiction or contingent statement
No. 2 only.
Use symbols to write the logical form of the following arguments. If valid, iden- tify the rule of inference that guarantees its validity. Otherwise, state whether the converse or the inverse error has been made. If you study hard for your discrete math final you will get an A. Jane got an A on her discrete math final. Therefore, Jane must have studied hard.
