Press the Begin button to have the program simulate 1000 coin flips. The blue line will track the percentage of flips that land on heads. The black line in the middle represents the 50% mark, where exactly 50% of all coin flips land on heads. Watch as the graph starts out chaotic but slowly approaches the 50% mark. The displays show the number of heads, the number of flips, and the percent of flips that land on heads. See inside for the list of all results.
