context: There is almost no chance that Daniel is in the garden. It is probable that Mary dropped the apple. It is impossible that Emily is a cat. We doubt that if either Mary dropped the apple, or Emily is a cat, then Lily is green. There is a better than even chance that if Daniel is in the garden, or Emily is a cat, then Greg is a swan. It is highly likely that if Emily is a cat, and Daniel is in the garden, then Julius is a frog.
