context: There is a better than even chance that John went to the hallway. We doubt that Bernhard is yellow. It is highly likely that Greg is gray. We believe that if John went to the hallway, and Greg is gray, then Julius is green. There is a very good chance that if Greg is gray, and Bernhard is yellow, then Brian is a rhino. Chances are slight that if either Greg is gray, or John went to the hallway, then Mary moved to the garden.
hypothesis: There is a better than even chance that mary moved to the garden, or John went to the hallway.
