context: There is a better than even chance that Mary picked up the milk. It is probable that Lily is a frog. It is likely that Greg is yellow. It is probably not the case that if Greg is yellow, and Mary picked up the milk, then Sandra got the apple. We doubt that if Lily is a frog, or Mary picked up the milk, then John went to the bedroom. We believe that if either Greg is yellow, or Mary picked up the milk, then Daniel took the football.
