context: There is a very good chance that Mary picked up the milk. There is almost no chance that Brian is white. We doubt that Bernhard is a swan. It is probably the case that if either Brian is white, or Bernhard is a swan, then Sumit is bored. There is a very good chance that if Brian is white, or Mary picked up the milk, then Julius is a frog. Chances are about even that if Bernhard is a swan, and Mary picked up the milk, then Sandra left the apple.
