context: It is probably the case that Julius is a lion. It is likely that Mary is in the garden. It is highly likely that Brian is a rhino. We believe that if Julius is a lion, or Brian is a rhino, then Bernhard is white. Chances are slight that if Brian is a rhino, or Mary is in the garden, then Sandra grabbed the milk. It is improbable that if Julius is a lion, or Brian is a rhino, then John went to the hallway.
