This is a two part question my book gives as practice problem. I, however am struggling to construct logical proofs and the book does not have a key. Thanks in Advance! 2a. Construct a proof, using any method (or rules) you want, that the following argument is valid: Premises (3): – [A&B], – [B&C], A v C Conclusion: – B Be sure to explain your proof procedure. 2b. Construct a proof, using only the 10 basic (primitive) rules, that the same argument is valid.
