Learn about probability, specifically calculating one stage and two stage probability events. This course is ideal for beginners.

Introduction 
Probability refers to the likelihood or chance of something happening. It can be helpful to think of probability as a scale, ranging from the certain to the impossible.
The probability scale is a line with impossible things at one end and definite things at the other end. In the middle are things that are just as likely to happen as they are to not happen; we call this an even chance.

Here are some examples and their positions on a probability scale:
An example of something that is at one end of the scale and labelled impossible could be: ‘It is impossible to win the lottery if you haven’t bought a ticket!’.

The chances of any event can be shown on a probability scale from 0 to 1.

A probability of 1/2 tells us that the event has an even chance of happening.
