solve for "p" and the tangent eqn

[cyberlolz]

Hey guys,
i am very concerned and somewhat scared in away about the marks that i would receive for:

The question where we have to solve for "p" ... i got the wrong answer for it but i stated that the sum of the probabilities equals 1.... how many marks will i get for that ? out of 3

The next one is the tangent question.. solving for a c d... i differentiated it incorrectly, therefore a c d were incorrect also (4 marks) will i lose all the marks?

it would be shattering to lose 7 marks ( Plus some hidden mistakes that i haven't  picked up)


Thanks for ur help.

And if i got the right answer but it wasnt simplified??? for the p one

You'll probably get 1 mark for the p value one..
and maybe 1 for the tangent one.
i fucked them up too. i think i screwed majority of it.
methods is an ass

Cyberlolz:
You'd get at least 1, possibly two depending on where you made your mistake.
For the tangent question, it would be possible for you to get 1 or 2 marks, depending again on your mistakes and the examiner.

Dawson:
You'd definitely get 2 marks, possibly 3 depending on the examiner

in that case i serisouly hope for nice examiners!!!!
