Hello everyone,

In "Gambling Theory and Other Topics" Mason gives a formula you can use to work out how many sessions you will lose.

Solving for "X" with my own results I arrived at a figure of -0.11

In Mason's example, X = -0.13

He then wrote:

"From a normal distribution table, we see that -0.13 standard deviations corresponds to the 44.83 percentage point. This means that with the parameters given you should expect to be a loser in about 45% of your five hour playing sessions."

Could one of you with access to a suitable normal distribution table tell me what percentage -0.11 corresponds to?

I've tried finding one on the internet, but have been baffled by the amount and different types of table available.

Thanks,

- roGER

My favorite is:

normal calculator (http://www.swogstat.org/stat/public/normal_calculator.htm)

For your purpose, just put in -.11, and find 45.6%.
