context: There is little chance that Lily is white. It is impossible that Mary moved to the garden. It is probably not the case that John put down the apple. Chances are about even that if either Mary moved to the garden, or John put down the apple, then Daniel is in the garden. There is a better than even chance that if either John put down the apple, or Mary moved to the garden, then Brian is a frog. There is a very good chance that if Lily is white, and Mary moved to the garden, then Greg is a swan.
