Updated On: Jul 9, 2024
- (¬x ∧ y) ⇒ (y ⇒ x)
- (x ∧ ¬y) ⇒ (¬x ⇒ y)
- (¬x ∧ y) ⇒ (¬x ⇒ y)
- (x ∧ ¬y) ⇒ (y ⇒ x)
Hide Solution
Verified By Collegedunia
The Correct Option is B, C, D
Solution and Explanation
The correct option is (B) : (x ∧ ¬y) ⇒ (¬x ⇒ y), (C) : (¬x ∧ y) ⇒ (¬x ⇒ y) and (D) : (x ∧ ¬y) ⇒ (y ⇒ x).
