I have a discrete 1 question (eng mathematics)

I hope u can solve the question easily (its better If u can understand the hint and solve the question like the photo)

And if u can write the answer clearly or using a computer

Show the argument below is invalid

p −→ ¬q

(¬q ∧ r) −→ ¬s

¬p ∧ ¬r

s ∨ p ∧ m

∴ s −→ m

Thank you for your response, since it was not included in the response, is it possible to provide the logics you applied? Example for: p ∧ r , q ∧ r , p ∧ q, I know that it would be "If both A & B are true then A ∧ B is true otherwise false. I do not know how to denote statements with more than 2 variables. Therefore showing this will help me to understand. Thank you. Specifically, p ⊕ q ⊕ r p ∨ q ∨ r ¬ p ∧ r ∨ q ∧ r ∨ p ∧ q p ∨ q ∨ r ((p ∨ q ∨ r) ¬ (p ∧ r ∨ q ∧ r ∨ p ∧ q)) (p ⊕ q ⊕ r) ↔ ((p ∨ q ∨ r) ¬ (p ∧ r ∨ q ∧ r ∨ p ∧ q))
