context: There is almost no chance that John went to the kitchen. There is a very good chance that Lily is green. We believe that Daniel left the football. Chances are about even that if Daniel left the football, or John went to the kitchen, then Gertrude is a wolf. Chances are about even that if Daniel left the football, and Lily is green, then Brian is gray. It is highly likely that if Daniel left the football, or John went to the kitchen, then Julius is a lion.
