context: We believe that Lily is a lion. Chances are slight that Greg is a frog. It is impossible that Brian is green. It is highly likely that if either Lily is a lion, or Brian is green, then Emily is a wolf. It is improbable that if Greg is a frog, and Lily is a lion, then Jeff went to the garden. It is probably not the case that if either Lily is a lion, or Brian is green, then Mary left the apple.
