Voici les propositions écrites en anglais simple :

Les énoncés donnés sont :
pp: Comfort studies hard. (Comfort étudie beaucoup.)
qq: She will pass the examination. (Elle réussira l'examen.)

c) p⇒qp \Rightarrow q
Ceci signifie "si pp, alors qq".

  • If Comfort studies hard, then she will pass the examination.

d) ∼p⇒∼q\sim p \Rightarrow \sim q
∼p\sim p signifie "Comfort does not study hard" (Comfort n'étudie pas beaucoup).
∼q\sim q signifie "She will not pass the examination" (Elle ne réussira pas l'examen).

  • If Comfort does not study hard, then she will not pass the examination.

e) ∼(p⇒q)\sim (p \Rightarrow q)
La négation d'une implication p⇒qp \Rightarrow q est logiquement équivalente à p∧∼qp \land \sim q.
Ceci signifie "pp et non qq".

  • Comfort studies hard and she will not pass the examination.
