context: Chances are slight that Julius is a frog. There is almost no chance that Mary is in the garden. It is probable that Lily is a rhino. We doubt that if Mary is in the garden, and Julius is a frog, then Bernhard is a lion. It is impossible that if Julius is a frog, and Lily is a rhino, then Winona is a mouse. We doubt that if either Julius is a frog, or Mary is in the garden, then Bill went to the kitchen.
