    No i got 1/210 but there were multiple a, b and r's so i did 1/210 x 3!2!2!, probably got it wrong but it is only 1 mark

    For the question with 9<X<20 I did P(X<20) - P(X<10), which is the same as (1-P(X>19)) - (1- P(X>9)) then just work it out ...

    Is that right?

    I did exactly the same and I don't see why it's wrong?
