context: It is highly unlikely that Brian is yellow. It is probable that Yann got the milk there. There is almost no chance that Bernhard is gray. It is probably the case that if either Bernhard is gray, or Yann got the milk there, then Lily is white. We doubt that if Bernhard is gray, and Yann got the milk there, then Julius is a rhino. It is probably not the case that if either Brian is yellow, or Bernhard is gray, then John went to the garden.
