context: It is improbable that Brian is a rhino. There is a very good chance that John moved to the garden. There is little chance that Greg is yellow. It is improbable that if either Greg is yellow, or Brian is a rhino, then Mary went to the office. It is probably not the case that if either Brian is a rhino, or John moved to the garden, then Bernhard is a swan. We doubt that if either Greg is yellow, or Brian is a rhino, then Lily is a lion.
hypothesis: It is impossible that lily is a lion, and Mary went to the office.
