context: It is highly unlikely that Julius is a swan. It is unlikely that Daniel is in the garden. Chances are about even that Bernhard is yellow. We doubt that if Daniel is in the garden, and Bernhard is yellow, then Lily is a rhino. It is probable that if Daniel is in the garden, and Julius is a swan, then Mary moved to the garden. It is probably not the case that if Bernhard is yellow, and Julius is a swan, then Greg is white.
