context: We doubt that John went to the garden. It is certain that Bernhard is a swan. There is a very good chance that Emily is a wolf. There is little chance that if Emily is a wolf, or John went to the garden, then Brian is green. It is highly likely that if either Emily is a wolf, or John went to the garden, then Mary left the apple. There is almost no chance that if Emily is a wolf, and John went to the garden, then Lily is a frog.
hypothesis: There is a better than even chance that john went to the garden, and Lily is a frog.
valid_hypothesis: It is impossible that john went to the garden, and Lily is a frog.
invalid_hypothesis: There is a better than even chance that john went to the garden, and Lily is a frog.
