Random Bracket Picking
The NCAA Basketball "Big Dance" is in full swing....with only four teams still in play. Using your great basketball acumen, many of you probably filled out a bracket as part of an "informal" betting pool. But, would you have done just as well by flipping a coin at each decision point, Heads = School A and Tails = School B?
Science Daily once published an article addressing this question, and provided some fascinating information:
 A person using a coin to randomly complete the full bracket for 65 teams has one chance in more than 18 quintillion of picking the winner in each pairing
 If every person on Earth could fill out a bracket every second, it still would take about one century to fill out all possibilities
 If a dollar bill represented each of the possible outcomes, the pile could be laid endtoend, making a distance equal to two round trips between earth and the big dipper
 As an analogy, suppose you wanted to hit your home with a bean bag from outer space...your chances of hitting your roof are better than your chances of correctly filling out all the tournament brackets using a coin flips
Don't you just love large numbers! And, I should add that Science Daily also includes an interesting video to accompany their article.
