context: It is improbable that John moved to the office. Chances are slight that Bill went to the bedroom. There is a better than even chance that Julius is a frog. It is almost certain that if Julius is a frog, and John moved to the office, then Brian is a lion. It is unlikely that if Bill went to the bedroom, and Julius is a frog, then Bernhard is a rhino. It is impossible that if either Bill went to the bedroom, or John moved to the office, then Greg is green.
