After finishing the preparation part for assignment 12, I found there may be some difference between CIE statistics and STEP statistics, just the question (iv):(b) and (c) in preparation

Thanks a lot
Re: CIE and STEP Statistics
If you're taking the CIE International A-Level (9709), and are doing the Statistics 1 paper (Paper 6), you should know the basic ideas of probability and combinatorics required to solve parts (iv)(b) and (c). Was there something in these problems or the solution that you didn't understand?
Probability
This question relies on the probability covered in GCSE- tree diagrams, conditional events etc. (as far as I recall - I haven't taught it for a couple of years but I don't think it will have changed that much!)
thank you for your help
thank you for your help, actually, I have finished this question using the combination which is the 5th modules on statistics 1 because I did not understand the answer.
with best wishes
