How many marks out of three do you think I will get for 12!-9!4!? instead of 8!x9P4

I don't know. Honestly I would say 1 at most.

The Solution for this can be one of.. 8!*9P4 or 8!*4!*9C4...

1 Mark for 8! 1 Mark for 9P4 and 1 mark for accuracy.

Yes probably.. since they say in their marking schemes .. for B mark .. like 8! seen .. *C6 seen and stuff like that.. so yeah you might get that one mark.

how much marks will i lose if i forget to convert all permutations and combinations answers to 3 s.f?
And how much marks will i lose if I wrote correct mean and var formulae but used incorrect 'p' in 'np' to calculate k and n.

No marks are deducted in permutations questions for not giving answers in 3. s.f

I had been waiting for such a post :) yes because I never saw any m.s emphasizing on rouding to 3 s.f in permutations coz how will they check whether ans was exact or not.
And how much sure are you ?
