MA3-CHAN-01, Quantify probability

Stage 3 (Years 5 and 6) ยท Mathematics ยท Chance

Runs chance experiments and puts a number on the probability of the outcomes.

MA3-CHAN-01 is an outcome from the NESA Mathematics K-10 Syllabus (2022), taught in NSW schools. Because Stage 3 spans Years 5 and 6, the worksheets below come from Year 5 and Year 6. Print them as PDFs, or generate a fresh one. Every maths answer key is computed in code, so it is never wrong.

Teaching guide

What students learn

Runs chance experiments and puts a number on the probability of the outcomes.

How to teach it

Order events from impossible to certain in everyday language, then quantify simple chances as fractions of the equally-likely outcomes.

Worked example
A bag has 8 balls. 2 are red. What is the probability of picking a red one? Write it as a fraction.
Answer: 2/8
Why: favourable 2 out of 8 total = 2/8

Generated and checked in code, so it is correct.

Watch out for

Assuming a rare-but-possible event is impossible, and thinking past results change the next independent outcome.
