Question

Suppose that you are given the following logical statement:
¬ P ∧ Q → ¬ R ∨ S
Based on our discussion of order of operations, which is the correct way to interpret
this?
(a) ¬(P ∧ ((Q → (¬R)) ∨ S))
(b) (¬(P ∧ (Q → (¬R)))) ∨ S
(c) ((¬P) ∧ (Q → (¬R))) ∨ S
(d) (¬P) ∧ ((Q → (¬R)) ∨ S)
(e) (¬(P ∧ Q)) → (¬(R ∨ S))
(f) ((¬P) ∧ Q) → ((¬R) ∨ S)
(g) ((¬P) ∧ (Q → (¬R))) ∨ S
(h) ((¬P) ∧ (Q → (¬R))) ∨ S
(i) (¬P) ∧ ((Q → (¬R)) ∨ S)
(j) ¬((P ∧ Q) → (¬(R ∨ S)))
