Data & Probability

Probability Tree Builder

Build multi-stage probability trees. Click a leaf to see the path highlight and compound probability calculate.

Why this tool helps: Students cannot track compound probability across multiple stages. The visual tree with highlighted paths makes it structured.

Year levels: Year 8, Year 9, Year 10 Curriculum: Australian Curriculum aligned
