StdDev/Probability question:
I was curious how to do the math for the following problem, which I am sure will help me with similar questions in the future. I want to know: At what number of hands will 1% of players with a theoretical (-1BB/100) and a standard deviation of 30BB/100 still be winning? I know similar questions have been covered in the past, but I need more of a walk through on how to solve this. Thank you, and Good luck. |

[/ QUOTE ] 1% of players will have a win rate at least S standard errors above average, where from Excel, S =NORMSINV(99%) =~ 2.33. We need S standard errors to be > 1 bb/100 to be winning. The standard error is 30/sqrt(N/100), so S*30/sqrt(N/100) > 1 N < 100*(S*30)^2 = 487,070 hands. |

Re: StdDev/Probability question:
Thank you very much for the quick answer. Unfortunately, I didn't really understand it.
Is it possible to give a walk through? |

I went back and made it an inequality, so that any number of hands less than this value will have at least 1% winners. See the explanation of this similar problem for a walk- through of the thought process. Here is another one. Let me know if you have any questions. |
