Gambler’s Ruin is a mathematical perception that indicates that a player with a defined bankroll is certain to lose to a player with an infinite bankroll, even in instances of even-money propositions. Most mathematicians find it easy to illustrate this perception by using the concept of wagering when flipping a coin. Gambler’s Ruin: Probability of Winning (when p = q and when p ≠ q) Let’s now calculate the probability of a player winning the entire game given k dollars and with a total of N dollars available, both for when that player’s probability of winning a given turn is 1/2 and for when it’s not 1/2. concept of probability theory and gambling The term gambler's ruin is a statistical concept, most commonly expressed as the fact that a gambler playing a negative expected value game will eventually go broke, regardless of their betting system. The original meaning of the term is that a persistent gambler who raises his bet to a fixed fraction of bankroll when he wins, but does not reduce it when he loses, will eventually and inevitably go broke, even if he has a positive expected value on each. This is commonly known as the Gambler's Ruin problem. For any given amount h of current holdings, the conditional probability of reaching N dollars before going broke is independent of how we acquired the h dollars, so there is a unique probability Pr{N|h} of reaching N on the condition that we currently hold h dollars. The gambler’s objective is to reach a total fortune of $N, without first getting ruined (running out of money). If the gambler succeeds, then the gambler is said to win the game. In any case, the gambler stops playing after winning or getting ruined, whichever happens first. Now repeat the process until one player has all the pennies. In fact, the chances and that players one and two, respectively, will be rendered penniless are.
Therefore, the player starting out with the smallest number of pennies has the greatest chance of going bankrupt. Even with equal odds, the longer you gamble, the greater the chance that the player starting out with the most pennies wins.
Since casinos have more pennies than their individual patrons, this principle allows casinos to always come out ahead in the long run.
And the common practice of playing games with odds skewed in favor of the house makes this outcome just that much quicker.
Dieser Vorteil liegt im Langzeit-Erwartungswert und kann als Anteil von der eingesetzten Summe ausgedrückt werden.
Er bleibt von Spiel zu Spiel unverändert, steigt aber rechnerisch mit zunehmender Spieldauer an, wenn er auf das Startkapital des Spielers bezogen wird.
Diese Rechnung geht auf, wenn der Spieler nie einen Wettgewinn zum Weiterspielen einsetzen würde. Ein idealisierter Wetter, der Euro einsetzt, würde nach dem Spiel 99 Euro behalten.
Die Abwärtsspirale geht weiter, bis der Erwartungswert sich der Null annähert: dem Ruin des Spielers. Der Langzeit-Erwartungswert entspricht nicht notwendigerweise dem Ergebnis, welches ein bestimmter Spieler erfährt.
The concept may be stated as an ironic paradox : Persistently taking beneficial chances is never beneficial at the end. This paradoxical form of gambler's ruin should not be confused with the gambler's fallacy , a different concept.
The concept has specific relevance for gamblers; however it also leads to mathematical theorems with wide application and many related results in probability and statistics.
Huygens's result in particular led to important advances in the mathematical theory of probability. The earliest known mention of the gambler's ruin problem is a letter from Blaise Pascal to Pierre Fermat in two years after the more famous correspondence on the problem of points.
Let two men play with three dice, the first player scoring a point whenever 11 is thrown, and the second whenever 14 is thrown.
But instead of the points accumulating in the ordinary way, let a point be added to a player's score only if his opponent's score is nil, but otherwise let it be subtracted from his opponent's score.
It is as if opposing points form pairs, and annihilate each other, so that the trailing player always has zero points.
The winner is the first to reach twelve points; what are the relative chances of each player winning? Huygens reformulated the problem and published it in De ratiociniis in ludo aleae "On Reasoning in Games of Chance", :.
Problem Each player starts with 12 points, and a successful roll of the three dice for a player getting an 11 for the first player or a 14 for the second adds one to that player's score and subtracts one from the other player's score; the loser of the game is the first to reach zero points.
What is the probability of victory for each player? This is the classic gambler's ruin formulation: two players begin with fixed stakes, transferring points until one or the other is "ruined" by getting to zero points.
However, the term "gambler's ruin" was not applied until many years later. Let "bankroll" be the amount of money a gambler has at his disposal at any moment, and let N be any positive integer.
And that he will be able to stop playing while he is in positive cash territory. The gambler is encouraged to gamble away his winnings.
Casinos have a house advantage house edge in games of chance. Casinos offer players free alcoholic drinks to encourage them to keep gambling.
