context: It is improbable that John discarded the milk. It is probable that Julius is a rhino. It is probably not the case that Lily is a swan. It is almost certain that if Julius is a rhino, and Lily is a swan, then Sandra left the football. We doubt that if Julius is a rhino, or Lily is a swan, then Daniel dropped the apple. It is impossible that if either Lily is a swan, or John discarded the milk, then Bernhard is white.
hypothesis: There is little chance that either Daniel dropped the apple, or Julius is a rhino.
valid_hypothesis: There is a better than even chance that either Daniel dropped the apple, or Julius is a rhino.
invalid_hypothesis: There is little chance that either Daniel dropped the apple, or Julius is a rhino.
