context: We doubt that Greg is a rhino. It is certain that Julius is gray. It is certain that Lily is a swan. It is likely that if Lily is a swan, and Greg is a rhino, then Brian is a lion. There is little chance that if either Greg is a rhino, or Julius is gray, then Jessica is a mouse. There is almost no chance that if Julius is gray, and Greg is a rhino, then Mary moved to the office.
hypothesis: Chances are slight that mary moved to the office, or Jessica is a mouse.
valid_hypothesis: Chances are slight that mary moved to the office, or Jessica is a mouse.
invalid_hypothesis: There is a very good chance that mary moved to the office, or Jessica is a mouse.
