context: It is improbable that Mary went to the office. We believe that Lily is yellow. It is impossible that John moved to the garden. Chances are slight that if Lily is yellow, and Mary went to the office, then Fred discarded the milk. It is highly unlikely that if either Lily is yellow, or Mary went to the office, then Brian is a frog. There is a better than even chance that if either Lily is yellow, or John moved to the garden, then Bernhard is white.
hypothesis: We believe that lily is yellow, or Bernhard is white.
valid_hypothesis: We believe that lily is yellow, or Bernhard is white.
invalid_hypothesis: It is unlikely that lily is yellow, or Bernhard is white.
