**Statistics: Probability**

Using and understanding probability – essential in modern life!

**Syllabus content**: SL 4.6, SL 4.7

I have made 5 worksheets and a Superpack to help with this:

- Venn diagrams
- Mutually exclusive and independent
- Conditional probability
- Discrete random variables
- SuperPack: Conditional probability
- Tree diagrams

You can scroll down below to see the pictures of the questions. You can download both the questions and mark scheme from the bottom of the page.
