context: There is almost no chance that Brian is gray. We believe that Mary went to the bedroom. It is highly likely that Julius is a rhino. It is certain that if either Julius is a rhino, or Mary went to the bedroom, then Greg is a frog. There is a better than even chance that if either Brian is gray, or Mary went to the bedroom, then Lily is a lion. There is a very good chance that if Mary went to the bedroom, or Julius is a rhino, then John put down the apple.
