context: There is a very good chance that Greg is a swan. There is almost no chance that Mary went to the office. There is a better than even chance that Bernhard is yellow. There is little chance that if Mary went to the office, or Bernhard is yellow, then Julius is green. It is almost certain that if Mary went to the office, and Greg is a swan, then Jeff discarded the milk. It is unlikely that if Bernhard is yellow, or Mary went to the office, then Lily is gray.
