Math Moment: Flipping Coins

Flipping coins

http://shazam.econ.ubc.ca/flip/

The more times you flip a coin, the closer you get to the statistical 1:1 ratio of heads to tails. This site lets you say how many coins to flip, and then shows you the results both with pictures and numbers. Try flipping increasing numbers of coins and see if you do indeed approach 50% heads. Try flipping a given number (say, 10) over and over again, and see how much it varies from time to time. Do small numbers vary more than big ones?
