context: We believe that Sandra got the football. It is improbable that Jeff dropped the apple. It is almost certain that Yann is tired. It is impossible that if either Jeff dropped the apple, or Sandra got the football, then Lily is a lion. It is probably not the case that if Sandra got the football, or Yann is tired, then Greg is a rhino. It is highly unlikely that if Jeff dropped the apple, or Yann is tired, then Bernhard is a swan.
