context: There is almost no chance that Brian is a swan. It is impossible that John went to the garden. It is impossible that Mary got the football. We doubt that if Mary got the football, or Brian is a swan, then Emily is a wolf. Chances are about even that if Mary got the football, or Brian is a swan, then Lily is a rhino. It is unlikely that if Mary got the football, and Brian is a swan, then Bernhard is green.
