context: There is a very good chance that Bernhard is yellow. It is highly unlikely that Mary moved to the garden. There is little chance that Julius is green. It is likely that if Bernhard is yellow, and Mary moved to the garden, then Greg is a swan. It is unlikely that if Julius is green, or Mary moved to the garden, then John went to the bedroom. There is almost no chance that if Julius is green, and Bernhard is yellow, then Brian is a frog.
