    And my brain says that gambling wields the greatest chance for 99% of the world population, to earn billions. xD

    Winning 27 times in a row has a 1 in 2916 chance of succeeding. On a world population of 6 billion people, this would mean that 2 million people would become billionaire's this way.

    Turning 6 billion dollars into 2 (how much is a million billion?) dollars. (Since all that loose would only loose a dollar most.).

    Unfortunatly, casino's don't have that kind of money. :P

    You know, when you think of it that way. You have a chance of becoming a billionaire by spending 2916 dollars.

    Ofcourse, chance is relative. You might not get the monies until you've spend like a million dollars. Out of the 6 billion dollars spend on the world population, only 2 million get the win. If you keep ending up on the wrong side, tough luck. :P

    I dont know how to play roulette, but even if you have a 50% chance of winning in one go. The probablity of winning 27 in a row is
    (1/2)^27. Which is like 1/7,450,580,596,923,828,125.

    This assume all the chances are independent.

    Ehh, probability factor are mathematical terms to reach near certainty. But I doubt you would need to flip a coin 7,450,580,596,923,828,125 times until you have throw heads 27 times in a row in actual practice.

    Maybe even longer, but when you have time write a program, with a random function
    and see how many times it will take before you get heads 27 times.

    I am going to do that now, since you said maths is different than in practice.

    Well, I maybe worded it wrongly.

    All I'm saying is that it's a parabolical function.

    The chance to get close to the mathematical number 1 is parabolical, 1/100000 might already have a 90% chance, even though to reach as close to 1 as probability applies, is 1/7,450,580,596,923,828,125

    So, in practice, you will most likely reach the winning number WAAAAY before the mathematical probability factor.

    import java.util.*;
    public class CoinToss {


    public static void main(String args[]){
    int count;
    double tries = 0;
    int end = 20;
    count = 0;
    Random rand = new Random();
    while(count < end){
    tries++;
    int num = rand.nextInt() % 2;

    if(num == 0){
    count = 0;
    }else{
    count++;
    }

    if(tries%100 == 0){
    System.out.println("The number of Tries: "+tries);
    }
    }
    System.out.println("The number of Tries: "+tries);

    }

    It works up to 20 but crashes on 27.

    Yes sometimes it might come before in practice but the mathematical value you gives the most likely value.
