context: It is impossible that Bernhard is white. It is certain that Sandra grabbed the milk. It is almost certain that Lily is a rhino. We believe that if Lily is a rhino, or Bernhard is white, then Greg is green. Chances are about even that if Bernhard is white, and Sandra grabbed the milk, then Emily is a cat. It is highly likely that if either Sandra grabbed the milk, or Bernhard is white, then Julius is yellow.
