context: It is highly likely that Greg is yellow. It is certain that Brian is a lion. It is impossible that Julius is a frog. It is highly unlikely that if Julius is a frog, and Brian is a lion, then Emily is a mouse. We doubt that if Julius is a frog, and Brian is a lion, then Daniel got the milk. Chances are slight that if Brian is a lion, and Greg is yellow, then Bernhard is green.
