context: Chances are slight that Mary went to the hallway. We doubt that Bernhard is yellow. There is a better than even chance that Antoine is hungry. It is likely that if Bernhard is yellow, and Antoine is hungry, then Daniel left the apple. We doubt that if Antoine is hungry, or Mary went to the hallway, then Greg is a frog. It is probable that if either Bernhard is yellow, or Mary went to the hallway, then Julius is a rhino.
