Probability+Line



=Probability Line= [|Probability] is the **chance**that something will happen. It can be shown on a line. The probability of an event occurring is somewhere between impossible and certain. As well as words we can use numbers (such as fractions or decimals) to show the probability of something happening: Here are some fractions on the probability line:
 * Impossible is **zero**
 * Certain is **one**.

We can also show the chance that something will happen: a) The sun will rise tomorrow.

b) I will not have to learn mathematics at school.

c) If I flip a coin it will land heads up.

d) If you have a choice of red, yellow, blue or green you will choose red.

Between 0 and 1
> This is because 0 is impossible (sure that something will not happen). > This is because 1 is certain that something will happen.
 * The probability of an event will **not** be less than 0.
 * The probability of an event will **not** be more than 1.
