Chance & Data
Describe chance, calculate probabilities, and summarise data with mean, median, mode and range.
What your child learns
- Probability = favourable outcomes ÷ total outcomes
- Find mean, median, mode and range
- Count combinations and outcomes systematically
Example
A bag with 3 red and 2 blue marbles: P(red) = 3/5.

- even chance
- likely
- certain
Show the answer
Answer: unlikely
It is unlikely.

Question 2 · Level 3
A fair 4-sided dice is numbered 1 to 4. What is the probability of rolling a number less than 3?
Show the answer
Answer: 2/4
2 out of 4 = 1/2.
-
Question 3 · Level 5
Two fair dice are rolled and the numbers added. What is the probability the total is 5?
Show the answer
Answer: 4/36
4 of the 36 pairs make 5: 1/9.
Try it at home
Roll a dice 30 times, tally the results and compare to what you expected.
Key takeaway
Probabilities are always between 0 (impossible) and 1 (certain).
