context: It is certain that Mary moved to the garden. Chances are slight that Brian is green. There is little chance that Julius is a rhino. It is impossible that if Julius is a rhino, and Mary moved to the garden, then Antoine is hungry. It is improbable that if either Mary moved to the garden, or Brian is green, then Greg is a swan. We doubt that if Brian is green, or Julius is a rhino, then Bernhard is yellow.
