Need this answer.Thank you
I need #11 and #13 DIRECTIONS: For each proof, you must include (i.e., write) the premises in that proof. I do not want to see any proofs without premises. Do not use any transformation rules (e.g. contraposition) in your proof other than DN. Only use the eight inference rules. YOU CANNOT USE CONDITIONAL PROOF (CP), INDIRECT PROOF (IP), OR ASSUMED PREMISES (AP). You will lose points if you use any of the inference rules Resolution, Contradiction, Transposition,
Good day.. this is all about Discrete Mathematics subject..please do help me with creating a solution for the following questions.just the solution and correct me if im wrong with my answer. thankyou
Answer 2 and 3 in the question. Please make sure the answers are correct. This question is in three parts. Given the premises: If the steak is well done, it’s overcooked. If the steak is overcooked, the fire alarm will go off. Either the batteries have been changed or the fire alarm will not go off. The batteries have only been changed if the ladder is in the room. The ladder is not in the room. Conclude that the steak is not well done. 2. These premises don’t make sense in the real world. Why? 3. How can you change the premises so that they make sense in the real world?
