Probabilitiy is all about finding the chance of something happening.
One thing you will be expected to do is to say which of two events is more or less likely.
To do this, we use the probability scale.
There's a couple of things to notice here.
The scale starts of at impossible at the left and gets more likely unitl we hit certain at the right.
The probability scale starts at 0 (impossible) and ends at 1 (certain)
We'll focus on the numbers later, let's just look at words today.
Examples: On the probability scale above, where would you place the following events.
1) You throw a coin and get a head.
Ans: This is an even chance, so it would go at point D.
2) You roll a dice and get a 6.
And: This is very unlikely so it would go at point B
