context: There is almost no chance that Greg is a rhino. Chances are about even that Mary moved to the office. There is a very good chance that Yann is tired. There is almost no chance that if either Mary moved to the office, or Yann is tired, then Lily is a swan. It is impossible that if Yann is tired, and Greg is a rhino, then John went to the garden. It is probably not the case that if Greg is a rhino, and Mary moved to the office, then Emily is a wolf.
