context: We doubt that Bernhard is white. It is impossible that Greg is a frog. It is almost certain that Brian is yellow. It is certain that if Brian is yellow, or Bernhard is white, then Lily is a lion. There is little chance that if Bernhard is white, or Greg is a frog, then Daniel grabbed the milk. Chances are about even that if either Greg is a frog, or Brian is yellow, then Gertrude is a cat.
