(the $10,000 is reserved for playing poker only so it cant use it to buy the book and I wanted to minimize the chance of ruin to simplify the problem.)
Thanks
Obviously i am not taking OP literally, seeing it as an example of question of relevant math not as a real life idea for the specific example. Because if the book is of any value to an already experienced player , buying it precisely before playing will make it even better than the other way around. So its not reasonable to worry about such things other than for mathematical purposes.
Are you asking if one has a Brownian motion for example of given EV and sd what is the time needed to have at the end of that interval a 95% probability to have acquired that profit or how much time is needed in advance to plan for playing so that there is a 95% chance to have been ahead by at least that at some point before the end of that time interval?
