Calculating Rate of Return on InvestmentSay you went to the race track every day and bet on 3 horse races. You are very good at what you do and are able to pick the correct horse 55% of the time. The amount you wager on each race is 5% of your current bankroll which you calculate after each race. Each time you win a race by picking the correct horse you add 5% to your bankroll. Each time you are incorrect you lose 5.5% of your bankroll. #2 20130213 14:18:29
Re: Calculating Rate of Return on InvestmentHi nflguy;
I do not believe that the order counts. Last edited by bobbym (20130213 14:40:02) In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20130213 14:59:29
Re: Calculating Rate of Return on InvestmentThat answer is fine if we were discussing continuous values. But we are talking about discrete values. There is a smallest unit of currency. After 232 straight losses you would have less than a penny. Essentially you are broke. In mathematics, you don't understand things. You just get used to them.

Re: Calculating Rate of Return on InvestmentVirtually impossible and really impossible are not the same thing. It does not have to be 232 in a row. It just has to be 232 more losers than winners. Yes, it is a longshot but it changes the problem. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Calculating Rate of Return on InvestmentOk so if you have a starting bankroll of $5000 how long would it take to turn that intial $5000 into 1 million dollars AND what are the chances you end up going bankrupt if you dont reach the goal. OR you can say that if you go bankrupt you are allowed to replinish the starting $5000 again. #8 20130213 15:16:03

Re: Calculating Rate of Return on InvestmentHi;
One more thing now. "Chances," refers to a probability, but your original question wanted how long. Which do you require?

Re: Calculating Rate of Return on InvestmentLook it up on google and stay clear of wikipedia. They are no good unless you already know the subject. In mathematics, you don't understand things.
