Some questions to delve a little deeper into the understanding of probability and tree diagrams. The first two are fairly standard (I)GCSE fare but subsequent questions become more complex with questions 5 and 6 requiring the solution of quadratic equations if an algebraic approach is used. Suitable for KS4 students who are ready for something a little more challenging than the standard GCSE style question. Answers included.
A selection of excellent challenge and extension questions for tree diagrams. The last few even venture into the realm of quadratic equations, meaning your students should be prepared for anything the exam should dare to throw at them.
