context: We believe that Mary went to the kitchen. It is highly unlikely that Bernhard is gray. It is highly likely that Lily is a lion. There is a very good chance that if either Mary went to the kitchen, or Bernhard is gray, then Gertrude is a wolf. Chances are slight that if either Lily is a lion, or Mary went to the kitchen, then Julius is gray. There is a better than even chance that if Bernhard is gray, and Lily is a lion, then Greg is a rhino.
