I have used this booklet extremely effectively with students in Y9, Y10 and Y11. It contains the most typical questions that are seen in GCSE exams. There are eight ‘standard’ probability trees for the students to complete and answer questions on, the requirements of each tree gradually getting more complex. Replacement and non-replacement scenarios are included. Note that the trees in this booklet have two branches and are symmetrical [Non-symmetrical trees are covered in a different workbook which I will upload sometime in the future]

Note that the booklet is designed to be printed as A4, but I usually reduce it to A5 and it still does the job.
