    • Spinner.  Run the spinner, change the colours.  Shouldn’t each equal sized sector be equally likely if a fair spinner?
    • Plinko.  A must see!  Just like The Price is Right.  If bouncing left and bouncing right are equally likely, shouldn’t the ball favour falling in the middle area?  See what happens after a thousand trials of ball drops.
