These notes should help to get you started on revising probability. Use these buttons to help you see the notes more easily.
Don't forget the different ways of showing the Sample Space
Remember n! is called factorial n, the easiest way to explain what it means is with some examples
3! = 1 x 2 x 3
6! = 1 x 2 x 3 x 4 x 5 x 6
On your calculator you should have a button to do this for you
- it is usually x! but you might have to press "shift" first.
We also use Venn Diagrams in some probability questions - sometimes we use the numbers in each group and sometimes the probabilities - see the page on Sets.
Thanks to "Mr Barton" and the TES (Times Educational Supplement) for the notes.
