Chance and Counting
Before chance is a fraction, it is a count. Bags of counters, fair spinners and how many different outfits you can make — every answer here is a whole number you can work out by counting carefully.
Every answer is a count, not a fraction. Writing a chance as a fraction lives in the Fractions tool.

Set your country and age — change
Setting an age keeps the questions at the right level for that age. It does not lock anything — you can still try any topic, at any age, in any order. Levels are a guide only, not a curriculum.
Your age is not saved anywhere. Your country is remembered only if you have switched saving on.
Saving your progress
Nothing is being saved. You can practise as much as you like — when you close the tab, the session is gone.
Why counting comes before chance
When people say a chance is “3 out of 8”, the hard part was never the fraction — it was working out that there were 8 things in the first place, and that 3 of them counted. Get the counting right and the fraction writes itself. Get it wrong and no amount of neat notation will save the answer.
The two that catch people out
- “How many ways” usually multiplies. With 3 tops and 4 pairs of shorts you have 12 outfits, not 7 — because every top can go with every pair. Adding tells you how many pieces of clothing you own, which is a different question.
- Read which group is wanted. “How many are NOT red” is asking about all the other colours. Answering with the reds is not a maths mistake at all — it is answering the question next to the one that was asked, and it is the most common slip here by far.
School levels
School levels are a guide only. They show where a skill is usually taught in each country and are not taken from, aligned to, or endorsed by any curriculum authority. Your school may cover it earlier or later.
