context: There is little chance that Greg is yellow. It is impossible that Mary got the milk. There is a better than even chance that Jeff moved to the office. We doubt that if Jeff moved to the office, and Greg is yellow, then Brian is gray. It is highly likely that if Jeff moved to the office, and Greg is yellow, then Bernhard is a lion. Chances are about even that if either Greg is yellow, or Jeff moved to the office, then Julius is a rhino.
