context: There is a very good chance that John went to the hallway. Chances are slight that Mary is in the cinema. There is a better than even chance that Daniel got the apple. It is probable that if John went to the hallway, and Mary is in the cinema, then Jason is bored. It is highly likely that if John went to the hallway, or Daniel got the apple, then Winona is a cat. We doubt that if Mary is in the cinema, and Daniel got the apple, then Greg is gray.
hypothesis: There is almost no chance that either Winona is a cat, or Greg is gray.
valid_hypothesis: There is a very good chance that either Winona is a cat, or Greg is gray.
invalid_hypothesis: There is almost no chance that either Winona is a cat, or Greg is gray.
