context: We doubt that Bernhard is a swan. It is probable that Julius is gray. Chances are slight that Mary moved to the office. It is impossible that if Bernhard is a swan, or Mary moved to the office, then Greg is a lion. There is almost no chance that if Mary moved to the office, and Julius is gray, then Bill is in the school. It is probably not the case that if Mary moved to the office, or Julius is gray, then Lily is white.
