context: It is unlikely that Mary went to the office. There is a better than even chance that Bernhard is white. We doubt that Lily is a rhino. It is probable that if either Bernhard is white, or Mary went to the office, then Gertrude is a wolf. Chances are slight that if either Bernhard is white, or Lily is a rhino, then Greg is green. It is certain that if Bernhard is white, or Lily is a rhino, then Brian is a lion.
