Click the Begin button to run the simulation. The program will simulate 1000 rolls of a fair 6-sided die. The average roll will be recorded by the blue line. The y-axis is the average roll (from 1 to 6) and the x-axis is the number of dice that have been rolled (from 0 to 1000). Watch as the graph fluctuates a lot for around the first 100 rolls and then stabilizes near an average of 3.5.
