context: There is a very good chance that Bernhard is green. Chances are about even that Fred went to the hallway. Chances are slight that Mary discarded the milk. There is a better than even chance that if either Mary discarded the milk, or Fred went to the hallway, then Daniel left the apple. It is unlikely that if Bernhard is green, or Fred went to the hallway, then Lily is white. It is probably not the case that if Mary discarded the milk, and Fred went to the hallway, then Greg is yellow.
