context: We doubt that Lily is a lion. It is probably not the case that Sandra got the apple. It is impossible that Brian is gray. It is impossible that if Brian is gray, and Lily is a lion, then Fred is in the office. It is improbable that if Lily is a lion, and Sandra got the apple, then Mary dropped the milk. It is unlikely that if Sandra got the apple, or Lily is a lion, then Bernhard is yellow.

valid_hypothesis: It is highly unlikely that bernhard is yellow, and Lily is a lion.
invalid_hypothesis: There is a better than even chance that bernhard is yellow, and Lily is a lion.
