context: There is almost no chance that Julius is a lion. There is a better than even chance that Lily is white. Chances are slight that Brian is white. We believe that if Brian is white, or Julius is a lion, then Sandra got the apple. It is highly likely that if either Lily is white, or Brian is white, then Mary went to the bedroom. It is impossible that if Julius is a lion, and Lily is white, then Greg is a frog.
