Oh God ... Please let it be!

 

[Albert Lianto]

hehe... Maybe. .

Otherwise, what would it have been? Think there was no other choice but to go with it.. Does CIE ever have typos tho?

 

[DarkEclipse]

Agh, I messed up the probability distribution part, I was in a hurry. Does anyone remember how many marks that question had?

 

[DarkEclipse]

My answers:
1)22
2)84/8008
3)1/4, (3/4)^4 x 1/4, (1/4)
4)i) 60,
5)IQ: 19, 103.4
6) Var(X)= 2.875,
7)316 days, binomial part= 0.840, 0.933
don't remember the remaining

I pretty much got the same, except for 3 iii) and 5 i)

 

[DarkEclipse]

Agh, just realized I made a silly mistake calculating Var(X). Shit. 1-2 marks gone

 

[The Sarcastic Retard]

Mine was 1/2. And no, you can't take 0s into account.

1/2 ?

 

[DarkEclipse]

I got that wrong, because my initial table was wrong.
Do you remember what that whole question was worth? (how many marks)

4 i guess

 

[DarkEclipse]

4 i guess

4 for entire question 6? I remember Var(X) had 3, and the last question had 2.

 

[DarkEclipse]

They'll award ecf right? If my table was wrong?

table copy wala was `1 mrk

 

[DarkEclipse]

table copy wala was `1 mrk

Yeah, but what was the total for the entire Q6?

 

[The Sarcastic Retard]

Yeah, but what was the total for the entire Q6?

1, 2, 2, 3 = 8 ?

 

[shazmina]

It was just a piece of cake <3

 

[DarkEclipse]

1, 2, 2, 3 = 8 ?

sure?

 

[The Sarcastic Retard]

sure?

As u said 2 questions were of 2 marks then yes, m sure.

 

[Anum96]

X^3 − x +6√3 = 0 Help :'(?

 

[Shujaat Khan]

Hell yeah its 480. 5! For 5remaining seats and 2!*2! For j and s arranged between 3seats while being together.
Also the 30 is obvious 6C4*4C4*2

But what about positive/even? Any experts I did it wrong and got 0.5

Yo any idea where you messed up? I got final ans 1/2 too but i remember doing the table fine(checked but adding everything they became 1. But i too messed up the varience my mean wasnt exactly 1
