context: It is impossible that Brian is white. It is probable that John went to the hallway. It is improbable that Sandra took the apple. We believe that if John went to the hallway, or Sandra took the apple, then Greg is yellow. We believe that if Brian is white, and Sandra took the apple, then Julius is a swan. Chances are slight that if John went to the hallway, or Brian is white, then Mary is in the bedroom.
