Question 6

Consider following two rules R1 and R2 in logical reasoning in Artificial Intelligence (AI) : R1 : From α ⊃ β and α/Inter β is known as Modus Tollens (MT) R2 : From α ⊃ β and ¬β/Inter ¬α is known as Modus Ponens (MP)

• Only R1 is correct.
• Only R2 is correct.
• Both R1 and R2 are correct.
• Neither R1 nor R2 is correct.
