Thanks for the solution

but for Q3 i)

isnt the range y>1

because 3/4 + (e^2x)/4

and e^2x > 1

therefore 3/4 + 1/4 = 1

Well that was depressing.
I told myself: "Tully, you are going to cry if you look at those solutions".
I looked at them, and then I cried.

EDIT: Anyone know what I would need to get scale E4 for this exam, assuming my ranks won't effect me?

The question is asking for the probability of getting at least one INCORRECT answer .. not CORRECT

so shouldnt the answer be 1-(1/4)^5
