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.

Hello, I have checked the answers again and they are all correct. Perhaps you'd like to say which answer you think is incorrect and I'll explain how the answer has been calculated. They are supposed to be challenging problems so perhaps you should try some easier questions next time?
