context: There is a very good chance that Greg is a frog. It is probably the case that John got the apple. There is a better than even chance that Mary moved to the office. There is little chance that if John got the apple, or Mary moved to the office, then Lily is green. We doubt that if Greg is a frog, or Mary moved to the office, then Emily is a mouse. It is almost certain that if either Mary moved to the office, or Greg is a frog, then Brian is a rhino.
