context: It is certain that Emily is a sheep. There is little chance that Mary is in the park. There is little chance that Bill went to the hallway. It is highly likely that if Bill went to the hallway, and Mary is in the park, then John left the football. It is unlikely that if either Mary is in the park, or Emily is a sheep, then Lily is white. It is probably the case that if Mary is in the park, and Emily is a sheep, then Bernhard is yellow.
