standard deviation dealing cards
First, here are some calculations, tell me if they are wrong. These are for getting dealt one hand in Texas Holdem.
P(2 aces) = 6 ways to get 2 aces / C(52,2) ways to get two cards = .005 So, after N hands, the EV of 2 aces is .005N. I need the standard deviation in order to find out how likely (or unlikely) it is to get deal aces x times in N hands. Any help? |

Re: standard deviation dealing cards
For n trials, this is the binomial distribution with p = .005.
Thus the standards deviation is sqrt(n*p*q) where q = 1-p. However, do not try to use the normal approximation to the binimial unless N is very large (since is p is so small here). Here's a link with more: http://www.stat.wvu.edu/SRS/Modules/.../binomial.html |
