Edit: People have noticed that he has quite a few errors. ie pi/6 instead of pi/3, and 666 days instead of 100.

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

No, e^2x > 0, not 1

 

[Aerath]

Nah, Terry Lee is correct for y > 3/4

 

[hp91]

for q4)iii) should the answer be 1-(3/4)^5? beacuse we are finding atleast 1 correct answer

 

[Top Secret]

Terry must seriously find something else to pass time.

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?

It'd be even sadder if he comes on bos, sees people say his solutions are wrong and then goes and changes it!

 

[Puttah]

Also

4a iii) It should be 1-(1/4)^5


Why did I even look at the answer? I look at the solutions then I look at myself and think... you retard...

edit: wait, wtf, 4a iii) was right? oh crap... *looks at self again*... you retard...

 

[annabackwards]

Fml.

 

[lychnobity]

oh fml, i got the probability wrong. Shit.

 

[vivien023]

for q4)iii) should the answer be 1-(3/4)^5? beacuse we are finding atleast 1 correct answer

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
