standard deviation
There's a phrase only a statistician could appreciate. Mathematically I understand it. But the first time I saw it, which was before I understood the math behind it, I thought to myself "this is just twisted useless gibberish of a sick mind".
Now that I have spent many years trying to understanding such things as: quantitative analytics, neural networks, genetic algorithms, etc etc etc. I'm convinced more than ever that it did in fact come from a "sick twisted mind"! |

If I start thinking about: Heisenberg Uncertainty Principle my head starts hurting.
Maybe not so bad, my head was hurting when this thread was about voltages, amps etc. too.
On edit: Hey, maybe I stumbled over something. The electrical problem may just be governed by that Heisenberg thing.. could be.

I thought I was posting on BadWeatherBikers.
Must have clicked on the CBS NUMB3RS tv show forum |

Nice smooth way to bring the tangent back around on topic! Excellent!
There is some truth there.... I've introduced all sorts of phantom problems trying to measure things to diagnose them. |

"How does the second scenario know it is different then the first scenario?"
I'd say it isn't any different. Who does the choosing of the door is inconsequential given that the opened door is known and always chosen to be empty.
Steve,
There's also roulette. I actually once won enough to pay for my cab fair playing roulette (Lisbon to Estoril and back). I had a system baybee. ![: ]](http://www.badweatherbikers.com/buell/clipart/proud.gif) Two reds? Bet black or vice versa. Same for even/odd. Lose the bet, double the bet next time. Yeah I know, fifty-fifty for each coin toss, but the odds of guessing "tails" correctly at least once go up with the total number (n) of tosses performed to something like...
P = 0.5n*n!/(n - 1)!
So if you guess "tails" every time, the first chance you'll hit is 50%; if the first toss comes up heads, your chance of hitting on the 2nd is 75%; if the 2nd toss also comes up heads, then your chance of hitting tails on the 3rd toss becomes 87.5% and so on, and so forth. If you are betting the same amount, you are losing bigtime. Thus the double each successive bet. Bring LOTS of cash, just in case...
$20 misses, then go to $40
$40 misses, then go to $80
$80 misses, then go to $160
$160 misses, then go to $320
$320 misses, then go to $640
$640 misses, then go to $1280
$1280 misses, now you are down by $2540, so then you go to $2560...
The house minimum and limit bets probably keep this kind of scheme to a minimum. |

The kicker is that when/if you finally hit before running out of cash or bumping into the betting limit, your winnings are a whopping $20. |
