Click on the button "Spin once" to spin the spinner. Click on the button "Spin lots" to spin the spinner a number of times. Change this number of times by changing the number of spins in the input box. Change the value associated with each portion of the spinner by entering different figures in the input boxes on the spinner. How is expected value related to the mean value of the game?
