# Probability for Kids

*(scroll this section to read all)*

Probability and chance are well worth learning about. Understanding the principles of probability can really help you make informed decisions throughout everyday life and also in your job. Being able to read and interpret probability data and graphs is a real help in many situations that involve evaluating the chances of something happening or the risks that we may wish to take. Something as simple as understanding the weather forecast or how insurance companies make their money are two small examples.

Using probability data is common in many job situations and in some technical vocations such as banking, insurance, marketing or politics it is absolutely essential. For an example of the benefits in certain job situations, read this article.

Also see our articles here on 'DATA' and 'STATISTICS'.

After you have a good understanding of Probability you should be able to:

- record random probability experiments
- understand the 0-1 scale for probability
- use Venn diagrams
- work with theoretical possibility spaces
- understand a little more about risk

The links we have selected below include fun and high quality activities, games and learning videos. If you work your way through these resources it will teach you about probability so that you use it in both everyday life and in your career.
