Probability in sports betting

We think it is important to familiarise yourself with this term before you find yourself placing bets on upcoming games. The truth is, no matter how good you are at predicting the outcome of sports events, chances are that every now and then you get it all wrong. There are so many aspects involved in this that you cannot be right at all times.

You need more than pure luck to win at this. You need to know about value. The purpose of this section is to make you familiar with value and bring you one step closer to understand probability. This is as important as the other sections in our sports betting guide , so pay close attention. In the first part of our basic probability section, we will talk about hit rates.

This is a term which is used to show how many successful wagers you have in relation to the amount of wagers you make in general. Hit rates are usually expressed as percentages. It should also be said that a high rate does not necessarily mean that you will increase your winnings in the long run. See what will we mean by going further down in our basic probability section.

Now, imagine that you placed bets on the favourites in a total of 19 matches in the first stages of a soccer tournament. That is pretty high. It looks like you could win a good profit, right? The truth is, any team that is expected to win a particular game is considered a favourite. Hence, the odds of that team winning will be low.

As a result of that, winnings are low too. If the odds of your favourites winning were 1. However, we mentioned that you hypothetically lost four of the games. So, you have to calculate your losses too. We will add a few more issues to worry about in the next paragraphs of our section about basic probability.

When you think about it, it seems that although you won, you lost money because the profits returned were very small. This is not to say that you should not bet on the favourites, though. Our purpose is to illustrate how you can have a high hit rate and still generate smaller to no profits. The reason for this is that your chances of winning are not reflected by your high rate. It serves to show how often you tend to make correct wagers. The quality of your bets is determined by value, and we will get to it in a few minutes, but first, we shall say a few things about probability.

Now, we are finally getting to explain what basic probability is and what role it plays in sports betting. By and large, this is a measure used to determine the likelihood of an outcome to happen. It is displayed as a decimal. More often than not, it is expressed as numbers between 0 and 1, where 1 suggests certainty and 0 suggests impossibility. In addition, you might also encounter basic possibility expressed as a percentage.

The former suggests certainty and the latter suggests impossibility. There are many situations in which you can calculate basic probability very accurately. For example, let us have a look at a coin. You know that tossing it can only result in two outcomes: the coin will either come up heads, or it will come up tails. This is quite easy to predict right? There is no way that another outcome occurs. It is the same with a roll of a dice. As you know, a die has six different sides, therefore six outcomes are possible when throwing it.

There is an approximately Given that there are numerous factors involved, there is no chance to measure the exact probability of a result. On the contrary, your calculations will be based on what you believe will happen during the game.

However, you, the bettor, are not the only one that does that. The bookmakers follow the same trend. However, you need to understand that their calculations do not involve only the probabilities of a certain outcome. They also make some adjustments to make sure that no matter whether they end up right or wrong, they are on the winning side.

In other words, they always go above and beyond to make the odds in their favour. This does not mean that there is no way to use things to your advantage. However, it is not that easy. Keep reading to learn more about probability to improve your chances of getting it right and beating the bookmaker. In short, this is a measure determined by dividing 1 by the odds note that it should be decimal odds.

So, it serves to show what the odds express that the possibility of a result will be. The odds were and remain 50 to 50, but the odds 2. Of course, you need to tackle 2. If, when playing in a casino, for example, roulette, the probability of a particular result is always known, then in betting on sports you can never calculate the exact probability.

And, actually, for this reason betting compares favorably with the casino. You can always find bets that are more likely to be set by the bookmaker. How to do it? There is no developed method for calculating the probability that would most accurately determine the odds.

This is impossible because of the impact on the result of many factors, the unpredictability of sport in general. For example, programs or formulas where you could enter data and get an approximate result. However, the known algorithm of actions to determine the probability of outcomes. Consider its stages. By itself, the statistics do not allow to get even an approximate probability. Recall the probability theory, which states that previous events do not affect the probability of future ones.

But statistics serves as a starting point, a base, because you need to push off for some reason. Having determined the initial probability using statistics, then we should analyze the match, taking into account as many factors as possible. Consequently, after studying the influence of each of them, corrections are made in the calculated probabilities. It is at the second stage that everything depends on how well the player understands the kind of sport he bets on. No matter how much one wants to understand and structure everything, it is impossible to accurately calculate the odds and determine how a particular factor affects the probability.

For each sporting event, a situational approach is needed. Fix the material of the previous paragraph by example. We will evaluate the Arsenal-Liverpool match and study the main line. The odds are as follows: Arsenal win — 2. Translate quotes into probability. And we get the following: Home — Now we will calculate the probability, after which we compare it with the bookmaker odds and determine the value, if there is any.

Immediately, we note that all the statistics and factors are conditional. Arsenal in the last 10 home games scored 8 wins and tied 2 times. Liverpool in the previous 10 away games won 6 times, and there were 2 draws and 2 losses. After that, we proceed to the second stage — consideration of various factors. First of all, we pay attention to injuries and disqualifications. The guests have almost no losses, while the hosts lost due to damage to the central defender and the left insider.

Also in the process of pre-match analysis, we learn that Liverpool rested for two days more, while Arsenal played its previous match three days ago. Fatigue may affect. In the last five games, two wins of Liverpool and three draws. No other significant factors were identified, therefore we are finishing the analysis. The more factors taken into account, the higher the chances of correctly determining the probability.

The difficulty is that there are no methods for objectively assessing the probability of a sporting event. The subjective opinion of the player evaluating the match plays a crucial role in the assessment of probability.

But there is no other way than the trial and error method. It is necessary to try, use different approaches, improve your methodology, which will allow you to accurately calculate probabilities with experience.

If you notice, the total of these probabilities is This is because the odds on display are not fair odds. The bookie has an edge built into the odds. According to a study published in the Journal of Gambling Studies , the more hands a player wins, the less money they are likely to collect, especially with respect to novice players. Behavioral economics comes into play here. A player continues playing the lottery , either in hopes of a big gain that would eventually offset the losses or the winning streak compels the player to keep playing.

In both cases, it is not rational or statistical reasoning but the emotional high of a win that motivates them to play further. Consider a casino. The house wants you to stay and continue playing. Naturally, the games offered by the casino have a built-in house edge, although the house advantage varies with the game.

Moreover, novices find it particularly difficult to do cognitive accounting and people often misjudge the variance of payouts when they have a streak of wins, ignoring the fact that frequent modest gains are eventually erased by losses, which are often less frequent and larger in size. A betting opportunity should be considered valuable if the probability assessed for an outcome is higher than the implied probability estimated by the bookmaker. Furthermore, the odds on display never reflect the true probability of an event occurring or not occurring.

The payoff on a win is always less than what one should have received if the odds had reflected the true chances. Science Daily. Journal of Gambling Studies. Business Essentials. Trading Psychology. Wealth Management. Auto Loans. Your Money. Personal Finance. Your Practice. Popular Courses. Key Takeaways The three types of odds are fractional, decimal, and American. One type of odd can be converted into another and can also be expressed as an implied probability percentage.

A key to assessing an interesting opportunity is to determine if the probability is higher than the implied probability reflected in the odds. The house always wins because the bookmaker's profit margin is also factored into the odds. Article Sources. Investopedia requires writers to use primary sources to support their work. These include white papers, government data, original reporting, and interviews with industry experts. We also reference original research from other reputable publishers where appropriate.

This fact forms the basis for some systems where it is possible to overcome the house advantage. In some games an advantage may go to the dealer, the banker the individual who collects and redistributes the stakes , or some other participant. Therefore, not all players have equal chances to win or equal payoffs.

This inequality may be corrected by rotating the players among the positions in the game. Commercial gambling operators, however, usually make their profits by regularly occupying an advantaged position as the dealer, or they may charge money for the opportunity to play or subtract a proportion of money from the wagers on each play. The house must always win in the long run.

Some casinos also add rules that enhance their profits, especially rules that limit the amounts that may be staked under certain circumstances. Many gambling games include elements of physical skill or strategy as well as of chance. The game of poker , like most other card games, is a mixture of chance and strategy that also involves a considerable amount of psychology.

In order to ensure that chance is allowed to play a major role in determining the outcomes of such games, weights, handicaps, or other correctives may be introduced in certain cases to give the contestants approximately equal opportunities to win, and adjustments may be made in the payoffs so that the probabilities of success and the magnitudes of the payoffs are put in inverse proportion to each other. Pari-mutuel pools in horse-race betting, for example, reflect the chances of various horses to win as anticipated by the players.

The individual payoffs are large for those bettors whose winning horses are backed by relatively few bettors and small if the winners are backed by a relatively large proportion of the bettors; the more popular the choice, the lower the individual payoff. The same holds true for betting with bookmakers on athletic contests illegal in most of the United States but legal in England. Unhappily, these procedures for maintaining the influence of chance can be interfered with; cheating is possible and reasonably easy in most gambling games.

Much of the stigma attached to gambling has resulted from the dishonesty of some of its promoters and players, and a large proportion of modern gambling legislation is written to control cheating.
