context: It is highly unlikely that Julius is a frog. It is highly unlikely that John got the milk. It is likely that Emily is a wolf. We believe that if either John got the milk, or Emily is a wolf, then Mary dropped the milk. There is little chance that if John got the milk, or Emily is a wolf, then Fred went to the kitchen. It is certain that if Julius is a frog, and Emily is a wolf, then Lily is a swan.
