context: Chances are about even that Julius is green. There is little chance that Brian is gray. There is a very good chance that Winona is a mouse. There is a better than even chance that if Julius is green, or Winona is a mouse, then John moved to the office. It is probably not the case that if Julius is green, and Winona is a mouse, then Jessica is a cat. We doubt that if Brian is gray, and Winona is a mouse, then Bernhard is white.
hypothesis: There is a better than even chance that jessica is a cat, and Bernhard is white.
valid_hypothesis: It is impossible that jessica is a cat, and Bernhard is white.
invalid_hypothesis: There is a better than even chance that jessica is a cat, and Bernhard is white.
