A-level Statistics and Mechanics 2021 Practice Exam | Edexcel style exam questions
A paper I put together based on past Edexcel exam questions which will still be good revision for you if you are with another exam board.

Mistakes:
Q1 there should not be "gaps" in the table. The intervals should be 0 to 2, 2 to 6 etc.
5(ii) (a) I wrote an equals sign but it should be a "not equal to" sign.
5(ii) (b)
It should be (2/3)*P(C)=13/24 and so P(C) = 13/16 is the correct final answer. And actually for part (b) the question itself is wrong, the probabilities given are impossible. Apologies!
