Explanation Given information: The provided argument is, If Jimmy does not find the keys, he will do his homework. Jimmy does not do his homework. Show that Jimmy found his keys. Formula used: Let P and Q be two statement forms. Then the different laws of logical implication are, The modus ponens logical implication is represented as, [ P ∧ ( P → Q ) ] ⇒ Q The modus tollens logical implication is represented as, [ ( P → Q ) ∧ ∼ Q ] ⇒ ∼ P The disjunctive syllogism logical implication is represented as, [ ( P ∨ Q ) ∧ ∼ Q ] ⇒ P The constructive dilemmas logical implications are represented as, [ ( p → q ) ∧ ( r → s ) ] ⇒ [ ( p ∨ r ) → ( q ∨ s ) ] [ ( p → q ) ∧ ( r → s ) ] ⇒ [ ( p ∧ r ) → ( q ∧ s ) ]
