context: We believe that Daniel left the milk. It is almost certain that Mary got the milk. We doubt that Bernhard is a swan. It is impossible that if Mary got the milk, and Daniel left the milk, then Greg is green. There is almost no chance that if Daniel left the milk, or Mary got the milk, then Julius is white. There is a very good chance that if either Bernhard is a swan, or Daniel left the milk, then Lily is yellow.
