context: It is probable that John moved to the garden. There is almost no chance that Bernhard is green. We doubt that Julius is a swan. There is a very good chance that if either Bernhard is green, or Julius is a swan, then Jessica is a wolf. Chances are about even that if Julius is a swan, or Bernhard is green, then Mary went to the garden. It is unlikely that if either Bernhard is green, or John moved to the garden, then Greg is green.
