Probability Experiments
Describing chance in words, and testing it by doing the experiment.
What this lesson covers
Probability Experiments is a 8-part Class 4 Mathematics lesson. Each part makes one point and then hands over to the next, so it can be read in a sitting or picked up again at the part you stopped on. It defines the idea in plain words before using it, works through an example step by step, breaks the topic into its parts and compares them, shows where it is used outside the textbook, names the mistakes that cost marks in an exam, ends with a recap of what to remember.
How it begins
We describe how likely something is with words: certain, likely, even chance, unlikely, impossible. Certain and impossible are the two ends; everything else sits between them.
The 8 parts
- The language of chance
- Counting the outcomes
