context: It is almost certain that Brian is yellow. Chances are about even that Mary got the milk. Chances are slight that John moved to the garden. It is impossible that if Brian is yellow, and Mary got the milk, then Lily is a rhino. We doubt that if Mary got the milk, and Brian is yellow, then Greg is a swan. There is a better than even chance that if either Brian is yellow, or Mary got the milk, then Emily is a cat.
