context: It is impossible that Brian is gray. It is probably not the case that John went to the kitchen. It is almost certain that Emily is a wolf. We believe that if Emily is a wolf, or Brian is gray, then Greg is a frog. There is almost no chance that if either Brian is gray, or Emily is a wolf, then Lily is a lion. Chances are slight that if Brian is gray, and John went to the kitchen, then Mary is in the park.
