context: It is probable that Mary moved to the garden. We believe that John picked up the apple. It is probable that Lily is a frog. We believe that if Mary moved to the garden, and John picked up the apple, then Bernhard is a swan. It is probable that if John picked up the apple, and Lily is a frog, then Daniel grabbed the milk.
