context: There is a very good chance that Mary went to the bedroom. It is unlikely that Greg is a swan. It is impossible that Bernhard is yellow. It is unlikely that if Greg is a swan, or Mary went to the bedroom, then Bill is in the school. There is a better than even chance that if Bernhard is yellow, and Greg is a swan, then John discarded the apple. It is probably not the case that if Greg is a swan, and Bernhard is yellow, then Daniel got the milk.
