Probability has been used in many different fields over the years and it has been something that helped people in many situations. As the new coronavirus spread across the world, many have started talking about the probability of how many people it will infect, kill, etc.

The simplest way to define probability is to say how likely something is to happen. Whenever you are unsure of the outcome, you can use probability to understand the possible outcomes.

The easiest example that comes to mind is flipping the coin. There are two possible outcomes when it comes to flipping the coin: heads and tails. What is the probability of the coin landing on one of the sides? Since we are looking for one outcome, and there are a total of two, all we gonna do is to divide the number of ways it can happen to the total number of possible outcomes. In this situation, simply divide 1 to 2. So, the chance for the coin to land on heads is 50%.

Now, let’s talk about something that has more than 2 possible outcomes, For example, dice. In this case, there are 6 possible outcomes, now, let’s say that you want to know what is the probability of rolling 4 and 6. In this situation, we have two different outcomes that we want to know the probability of, and in total, there are 6 possible outcomes.

This means that the number of ways it can happen is two, and the total possible outcomes, 6. In this situation, we will have to divide 2 to 6.

There are many fields actively using probability and without it, it would be impossible for many of them to exist at all.

## How is probability used in sports

In sports, it is very important to have a good gaming strategy in order to be successful. For different types of games and competitions, best athletes and coaches frequently use probability to come up with different types of strategies that would work the best.

For example, in baseball, the coach has the ability to create a lineup according to the player’s batting average. If a player has a 200 batting average, for example, it means that he has gotten a base hit two out of every 10. Someone with a 400 batting average will be higher in the lineup since he has gotten 4 base hits out of every 10.

## The world of gambling and probability

Gambling is one of those fields where people are using probability very actively. There are many games in the world of gambling where probability can be used, for example, one could use it in every single one of the card games.

Also, it could be very actively used in Roulette. Let’s say that you are playing Roulette with 37 digits, you choose a number and wait for an outcome. The probability of you winning would be 1 divided by 37. But there are many other options of betting in roulette, for example, the probability of the ball landing on a red number is 18 divided by 38.

However, it seems to be very hard for many to trust probabilities in the world of gambling. In 2019, there was a study about roulette probability. During the study, some people were asked if they would use probability to play casino games such as roulette and many of them said that they would not. The study focused mostly on gamblers of online casinos, who said that strategies that they had never worked before.

Still, probability can be used in many different games, what types of cards you will receive while playing poker, where the roulette stops spinning, and many other things heavily depend on probability in the world of gambling.

## Probability is actively used in weather forecasting

People use probability every day of their lives without even realizing that they are using it. We enjoy some of the greatest examples of it while checking the weather every day. Meteorologists can not predict the exact weather, so they are using probability to say what is going to happen. For example, if your phone says that there is a 60 percent chance that it will rain, it means that in the case of 60 out of 100 days with the same conditions, it has rained.

Professionals also take a look at historical data in order to forecast for the day of the week and talk about possible weather trends.

The greatest thing about probability is that people are using it in their everyday lives without even realizing it. It helps us to make many different decisions by trusting the numbers, every time you decide to use an umbrella because of the weather forecast or are working on a new strategy for sports, you are using probability.

There are many fields where probability is being used on an everyday basis and it makes our lives easier. This mathematical chance of something happening has influenced many of our decisions, and it continues to help us make some of the hardest decisions every day.
