In this post, we are going to learn probability in a very simple way and we will give you a foolproof trick to pass your math exam!

What is the probability that you will eat spaghetti or salad? If you throw a coin, that it will land heads or tails? Or that you will roll 2 on a die?

The possibility that something will happen or not is what we know as **probability**.

The outcomes can be:

- Possibilities
- Impossibilities
- Insurance – what we are sure of.

We are going to explain with some examples.

#### You find this menu in a restaurant

It is **possible** that you will eat salmon, beef, or chocolate mousse, but it is **impossible** that you will eat pizza, hamburgers, or ice cream because they are not on the menu and **I am sure** that you will get something to eat.

Mathematics is a language and we can write the odds as fractions, decimals, or percentages.

#### Tossing a coin

Tossing a coin, the odds that it will land ”heads” is one in two since there are only two possible results. We express it as:

- As a fraction: 1/2 (a half).
- If we complete this division problem we get a decimal: 0.50
- And if we multiply it by 100 we will see the percentage, which means that we have a 50% chance that it will be heads or tails.

#### Throwing dice

Something similar happens with the example including dice. It is 1/6 possible to roll a 2, or 0.167 expressed as a decimal and 16.7% as a percentage.

If you would like to practice probability, you can try this decimal dice.

However, in reality, many events do not depend on probability, but on certain **factors and conditions**. Therefore, the great trick to help you pass your math exam is: complete your daily sessions with Smartick!, study, participate in class, eat healthily, and rest. If you follow this advice it is like you’ve rigged a coin or die before throwing it because you know beforehand that the result will be in your favor.
