context: We believe that Brian is yellow. It is probable that Lily is a frog. We believe that Greg is a lion. There is a very good chance that if Brian is yellow, and Greg is a lion, then Winona is a cat. We doubt that if Brian is yellow, or Lily is a frog, then Mary got the football. It is likely that if either Brian is yellow, or Lily is a frog, then Bernhard is white.
hypothesis: There is a better than even chance that bernhard is white, or Winona is a cat.
valid_hypothesis: There is a better than even chance that bernhard is white, or Winona is a cat.
