"WebbProof 12: The argument (AV B) A is a tautology, which means it is always true. We can prove this by assuming A is true, and then using the disjunction introduction rule (vI) to infer AVB. Since A is true, we can also use the conjunction elimination rule (∧E) to infer A. Therefore, we have shown that (AVB)A is true. " - The premises p ∧ q ∨ r and r → s imply
