context: We doubt that Bernhard is a frog. It is certain that Mary went to the hallway. We believe that Greg is green. We believe that if Greg is green, and Mary went to the hallway, then John took the football. There is a better than even chance that if Mary went to the hallway, or Bernhard is a frog, then Sandra got the apple. It is probably not the case that if Greg is green, or Bernhard is a frog, then Gertrude is a wolf.
hypothesis: There is a very good chance that sandra got the apple, or John took the football.
