context: It is highly unlikely that Mary moved to the garden. It is impossible that Winona is a mouse. Chances are about even that Julius is green. We believe that if Winona is a mouse, or Julius is green, then Jeff discarded the milk. It is probable that if Julius is green, and Winona is a mouse, then Brian is white. There is little chance that if either Winona is a mouse, or Mary moved to the garden, then Greg is a lion.
