Everyone is Lucky

October 29, 2009

Fun with Math, from Armen Alchian’s “Uncertainty, Evolution, and Economic Theory”:

Suppose two million Parisians were paired off and set to tossing coins in a game of matching. Each pair plays until the winner on the first toss is again brought to equality with the other player. Assuming one toss per second for each eight-hour day, at the end of ten years there would still be, on the average, about a hundred-odd pairs; and if the players assign the game to their heirs, a dozen or so will still be playing at the end of a thousand years!

    Why Parisians? Also, there would probably be many more, since coins aren’t perfectly fair.

  2. Because Parisians have low value in alternative uses?

    Today, of course, by law, they would only be allowed to toss coins for seven hours a day, not eight. But this was before the 35-hour workweek (and the plethora of jobs that were thereby created!) was instituted in France.
