context: It is probably not the case that Julius is a frog. It is highly likely that Brian is a swan. It is probable that Bernhard is gray. We believe that if either Bernhard is gray, or Brian is a swan, then Sumit is thirsty. There is a very good chance that if Julius is a frog, or Brian is a swan, then Greg is white. It is improbable that if Brian is a swan, and Bernhard is gray, then John discarded the milk.
hypothesis: Chances are about even that john discarded the milk, and Brian is a swan.
valid_hypothesis: It is highly unlikely that john discarded the milk, and Brian is a swan.
invalid_hypothesis: Chances are about even that john discarded the milk, and Brian is a swan.
