Puppies and ping-pong balls

Imagine you are in a room alone with a Ping-Pong ball. If you repeatedly drop the ball from waist height, you can be fairly confident of correctly predicting that it will fall to the ground somewhere near your feet. We call this Scenario 1.

However, suppose now that an eager ball-chasing puppy is in the room with you and also that a strong electric fan is brought into the room, placed near you, and switched on. Now, when you drop the Ping-Pong ball, how certain can you be that the ball will land near your feet. Presumably much less certain, because the puppy might catch it or the fan might blow it off course. We call this Scenario 2.

Now suppose there is a pack of eager puppies in the room and a series of electric fans; someone has opened the window and a howling gale is blowing; and, furthermore, you are now obliged to stand on an electric treadmill programmed to randomly vary its speed! Now when you drop the ball, how confident are you that it will land near your feet? Indeed, how confident are you in making any prediction about where the ball might end up? We call this Scenario 3.
