context: We doubt that Greg is a lion. It is impossible that Lily is yellow. It is almost certain that Julius is a frog. It is probable that if either Julius is a frog, or Lily is yellow, then Gertrude is a mouse. There is almost no chance that if Greg is a lion, or Lily is yellow, then Fred went to the cinema. It is highly likely that if Greg is a lion, or Julius is a frog, then Sandra dropped the apple.
