context: It is highly unlikely that Lily is a frog. It is probably the case that Greg is yellow. It is certain that Sandra left the milk. There is little chance that if either Sandra left the milk, or Greg is yellow, then Bernhard is a lion. We believe that if Greg is yellow, and Lily is a frog, then Julius is white. Chances are slight that if Greg is yellow, and Sandra left the milk, then John went to the garden.
