context: Chances are slight that Lily is a rhino. We believe that Jessica is a mouse. There is a very good chance that Bernhard is green. We doubt that if either Jessica is a mouse, or Lily is a rhino, then Gertrude is a mouse. It is probable that if Bernhard is green, and Lily is a rhino, then Greg is a frog. It is certain that if Bernhard is green, or Jessica is a mouse, then Julius is gray.
