context: We believe that Fred discarded the milk. It is improbable that Lily is green. We believe that Julius is a lion. It is likely that if Lily is green, or Fred discarded the milk, then Daniel is in the garden. It is probably the case that if Julius is a lion, and Fred discarded the milk, then John went to the bedroom. Chances are about even that if either Julius is a lion, or Fred discarded the milk, then Gertrude is a mouse.
