Default Re: Basic Normal Distribution Question

I assumed an SD of 15, which is close enough. Actual SD's can vary between around 14 and 18, but most I've seen are 15 or 16.

Anyway, say you win at 1.5BB/100.

Over 10000 hands, your SE (the SD of the normal distribution in question) is SD/(sqrt(100)). 100 because 10K has 100 samples of size 100.

So if your SD is 15, then the amount you've won after 10K hands has a normal distribution with mean 1.5 and SD 1.5. Now you find the area under such a normal distribution from -infinity to 0 using a normal distribution calculator -- you can find one on google.

HTH,
