context: We believe that Mary moved to the garden. There is a very good chance that Lily is white. It is probably the case that Greg is a rhino. There is almost no chance that if Greg is a rhino, or Lily is white, then Winona is a sheep. It is unlikely that if Lily is white, and Mary moved to the garden, then Bernhard is gray. We doubt that if Mary moved to the garden, and Lily is white, then Sandra left the milk.
