context: We doubt that Lily is a lion. It is impossible that Mary went to the hallway. It is impossible that Julius is gray. It is highly unlikely that if Mary went to the hallway, and Julius is gray, then Jessica is a mouse. It is improbable that if Lily is a lion, or Julius is gray, then Bill moved to the garden. There is little chance that if either Mary went to the hallway, or Lily is a lion, then Winona is a cat.
