context: It is highly likely that Bernhard is a frog. It is unlikely that Julius is a swan. It is impossible that Mary put down the apple. We believe that if either Julius is a swan, or Mary put down the apple, then Fred is in the bedroom. We doubt that if Mary put down the apple, or Julius is a swan, then Emily is a cat. We doubt that if either Mary put down the apple, or Bernhard is a frog, then Bill went to the hallway.
