The premises are : ¬р^q, r→p, ¬r→s, s → t so the conclusion will be "t". Apply the following rules of inference.
Mam please explain in detail. I did not get it
Firstly, we can apply Simplification rule on premise (1) (¬p∧q) →¬p [5]. Next, we can apply Modus Tollens rule on premise (2,5) (¬p ∧(r →p))→¬r [6]. Next, we can apply Modus Ponens rule on premise (3,6) (¬r ∧ (¬r →s)) → s [7]. Similarly, we can apply Modus Ponens rule on premise (4,7) (s ∧ (s →t)) → t [8]. Hence, we will get t as conclusion.
