context: There is a better than even chance that John took the football. It is certain that Mary went to the garden. It is highly likely that Brian is gray. We believe that if John took the football, and Brian is gray, then Greg is a rhino. There is a very good chance that if John took the football, and Mary went to the garden, then Julius is green. It is probably not the case that if either Mary went to the garden, or Brian is gray, then Bernhard is white.
