context: It is probable that Bernhard is gray. We believe that Mary took the apple. There is a better than even chance that Brian is a frog. We doubt that if either Bernhard is gray, or Brian is a frog, then Lily is a lion. It is probably not the case that if Brian is a frog, or Bernhard is gray, then Fred went to the hallway. It is improbable that if either Mary took the apple, or Bernhard is gray, then John left the apple.
