context: It is almost certain that Mary went to the garden. We doubt that Sandra took the milk. There is a better than even chance that Lily is a frog. We doubt that if either Lily is a frog, or Mary went to the garden, then John got the apple. It is impossible that if Lily is a frog, or Sandra took the milk, then Bernhard is green. Chances are about even that if Sandra took the milk, and Lily is a frog, then Brian is gray.
