I understand that the contrapositive flips and negates the statement. But the rule states that Raimundo appears in every picture that Yakira does not appear in. I understand the contrapositive of that states Yakira appears in every photo that Raimundo doesn't, but logically that doesn't makes sense to me. Since the rule doesn't state that Raimundo ONLY appears in photos that don't have Yakira, why is it not possible that both Raimundo and Yakira are not in the photo?
