What this pack does

What pupils learn

Pack 4 taught you to calculate the probability of a single event. Now we connect an event to everything outside it. If event A happens or it does not happen, those two possibilities cover the whole probability space. That whole has probability 1. This lets us find missing probabilities without rebuilding every outcome count from scratch. 1 | Licensed to buyer: school/tutor/student Probability 5 | Student Pack

The mini-lessons

An event and not-that-event fill the whole probability space
Find the probability of not A
Sometimes the not-event is given first
Several outcome probabilities still have to total 1
The word “not” needs careful reading

Inside every pack

What each part of the page is for

Confidence check
Pupils tick how a topic feels before they start, and again at the end. There are no marks, so it's an honest picture of where they are.
Short mini-lessons
Each topic is split into small steps. Every mini-lesson opens with one big idea and a short, plain-English explanation.
Visuals for every idea
Diagrams such as a formula 'rule machine' or a place-value picture show the maths, so pupils can see it as well as read it.
Worked examples
Every method is modelled step by step before pupils try it, with each stage labelled so they can follow it on their own.
Scaffolded practice
Questions start with prompts (what do you need to find, follow the example, check it makes sense) and gradually ask for more independence.
Spot the trap
Common mistakes are named before pupils make them, and Mistake Detective questions ask them to find and fix errors.
Pause and think
Short 'explain it in your own words' prompts check that pupils understand why the maths works, not just how.
Teacher Pack with answers
Every pack comes with a Teacher Pack: all the answers, plus reteach cards saying what to watch for, what to say, and what to try if a pupil is still stuck.
