Practice questions, homeworks and assessments
Two worksheets, testing basic probability with dice, coloured balls and letters. The second worksheet is more difficult and introduces sampling with and without replacement.
Full solutions included.
Edit: May 2023 fixed question numbering
Edit: July 2024 added a Powerpoint for finding the probability with two events, explaining when to add and when to multiply the two probabilitiesReviews

Six "spiders" on probability. The first two are basic, the middle two are two events (independent) and the final two are two events (dependent). Some "legs" answer questions, some legs give the answer and ask for the question. They have been split this way so that you can use different "spiders" with different classes. These should encourage discussion and questions such as "Is that the only answer?" which should demonstrate understanding. Typos corrected.

where are the solutions?

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.
