context: Chances are about even that Bernhard is green. There is a better than even chance that Sandra left the apple. It is likely that Mary moved to the office. It is likely that if either Mary moved to the office, or Sandra left the apple, then Gertrude is a mouse. It is highly unlikely that if Sandra left the apple, and Bernhard is green, then Lily is a rhino. It is probably the case that if Bernhard is green, and Mary moved to the office, then Brian is yellow.
