context: Chances are slight that Mary went to the kitchen. We believe that Brian is a swan. We believe that Julius is green. It is impossible that if Julius is green, or Mary went to the kitchen, then Greg is a frog. We doubt that if Brian is a swan, and Julius is green, then Lily is yellow. It is likely that if Brian is a swan, or Mary went to the kitchen, then Bernhard is a lion.
hypothesis: There is a better than even chance that bernhard is a lion, or Mary went to the kitchen.
