Gamblers are Losers. Ha! Ha! HAFebruary 22, 2011
It comes from Alex Bellos who wrote Alex’s Adventures in Numberland (Bloomsbury) with some additions by Mathspig.
1. Ask each member of the class to guess, then write down on a piece of paper the result they imagine for tossing a coin 30 times .
2. Now ask them to actually toss a coin 30 times recording the result.
3. Then ask them to toss the coin one more time. Students who throw Heads will write their first results on the board. And tails their second results.
4. Finally, see if the class can guess which is which, and calculate the probability of getting those guesses right.
As Alex Bellos explains, we humans try and impose order on chaos. Our imagined results show a pattern. The real results are more… well, random. The problem is when we write HH we then think it must be Ts turn. It doesn’t matter how many Hs appear in a row, the probablity for the next flip producing a H is still 1:2. Therefore the random results for tossing a coin can have any number of Hs or Ts together!!!!!!!!!!! The longest recorded run for Black on the roulette wheel was 26. See an earlier mathspig post, The Wheel on the Roulette Table went round and round, round and round.
See if you can pick which of the following results A, B, C or D was guesswork. The other three are real coin flip results.
In fact, A was the guess.
Gamblers constantly think it’s time for a particular number to be drawn in loot or for a machine to pay out. And they are wrong. Sooooooo wrong……. This is called the gambler’s fallacy. More @ Prevent Gambling Addiction
DO YOU THINK GAMBLERS ARE LOSERS?
DO THE MATHS!!!!
Look at these Las Vegas Casinos …. This has all been paid for by LOSERS….
This …..The Excalibur Hotel Casino (below)
And this …New York, New York Hotel Casino
And this …The Luxor Hotel Casino
And this … The Venetian Casino
Are you feeling lucky, punk? Don’t bet on it!!!!!
On the other hand, a maths genius might not need luck. See Maths Makes Money post (following).
