context: There is a very good chance that Mary is in the bedroom. It is almost certain that Lily is a swan. There is a better than even chance that Brian is green. We doubt that if either Brian is green, or Lily is a swan, then John left the milk. It is highly unlikely that if either Mary is in the bedroom, or Brian is green, then Bernhard is gray. Chances are about even that if Brian is green, and Lily is a swan, then Gertrude is a cat.
hypothesis: It is probably not the case that either Mary is in the bedroom, or Lily is a swan.
