Understanding Probabilities in Casino Games: A Beginner’s Guide

Whether you’re playing a strategy-based game or one that is purely based on luck, probabilities play a major role in all casino games. They directly impact your chances of winning. Hence, understanding the probabilities in casino games can help you create better strategies, manage your bankroll, reduce risks, and avoid big losses.

What are Probabilities in Casino Games?

In simple words, probability is the likelihood of an outcome. Say, you flip a coin, the probability of landing heads or tails is 1/2 or 50%. In casino games, this gets a bit more complex, but the principle stays the same. In American roulette, there are a total of 38 slots on the wheel of which 18 are black. So, the probability of hitting black is 18/38 or 47.4%.

There is a key difference between dependent and independent events that must be understood when it comes to probabilities in casino games. For example, in slots or roulette, the outcome of the next spin will not be affected by the previous event. Whereas, in a game like blackjack, every move affects the probability of the next outcome.

What is a House Edge in Casino Games?

While probabilities are also used to calculate the betting odds and subsequent wins, there is another factor to be considered here. If you’re betting on an event like a coin toss that has two possible outcomes each with a 50% probability, you’d expect to win $1 on a $1 bet.

However, that is not the case. Casinos need to take a cut from the payouts to stay profitable, and that is the house edge. It is how the casinos make money. Your $1 winning bet on Heads should give you $0.96, considering a 4% house edge.

Here’s an example from a popular casino game. The true odds of landing a single number in roulette are 1/38 (2.63% probability). However, the payout odds offered by the live casino are 35 to 1. Calculating for probability based on these odds, we get a 1/36 of 2.77% chance of winning.

What this means is that the live casino pays you as if your chance of winning is 2.78%, but it is only 2.63%. In this case, the house edge is 0.15%. That is how much the casino makes from every payout.

Probabilities in Popular Casino Games

Let’s look at some other casino games and the role of probability.

Blackjack

This casino game is a mix of luck and skill. Understanding the odds and probabilities of different outcomes is at the heart of every decision you make in blackjack.

For example, the odds of going bust while holding a 12 are 31%.

You can make use of a basic strategy chart to learn all about the odds in blackjack and plan your every move accordingly.

Roulette

The probability of hitting a black or red is close to 50% while that of hitting a single number is 2.63% in the American version.

Poker

Here’s another casino game that requires skill. As such, it is crucial to learn the probabilities of different hands. For example, the odds of getting a flush are 0.2% while those getting a straight are 0.4%.

Conclusion

Learning the odds and probabilities is an important part of preparing yourself for playing casino games. Even in luck-based games, knowing the probabilities will keep you from committing the gambler’s fallacy and other misunderstandings such as “hot streaks” and “hot machines”. Knowing the probability of an outcome does not guarantee you a win, but it helps you make an informed choice and play sensibly.
