Lesson details
Key learning points
- Equations can be constructed when there is a known relationship between the probabilities of exhaustive events
- Equations can be manipulated and solved to find missing probabilities
- Algebraic statements can be created regardless of the way the probabilities are displayed
Keywords
Probability - The probability that an event will occur is the proportion of times the event is expected to happen in a suitably large experiment.
Common misconception
Pupils may be unsure whether a variable represents a probability, frequency or a particular outcome.
Variables can be used to represent either of these pieces of information. It can be helpful to start a problem by writing down what any variables represent (e.g. "Let x = the total number of marbles).

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
