context: Chances are slight that Bernhard is a frog. It is probable that Mary moved to the office. It is highly likely that Sumit is bored. There is a very good chance that if Sumit is bored, and Mary moved to the office, then Brian is a lion. It is unlikely that if either Sumit is bored, or Bernhard is a frog, then Julius is a rhino. We believe that if Mary moved to the office, and Sumit is bored, then Daniel got the football.
