How was 9709_w15_qp_62?

[DDanielAWE@]

Yep!

The second part of that Jon and Sarah was 240 rite?

It was combination

 

[DarkEclipse]

I know it was combination, I just did it in a different line of thought.

My 4(i) was 30 and my (ii) was 480 I think..
In 4(i), does J and S's ordering matter to multiply by 2? I got 30 from 2 x 6C4, the 2 coming from J and S possibly being in either taxi..

Question 3 was on probability, the different colored plastic robots..

 

[The Sarcastic Retard]

I got 30 too. :3

 

[DDanielAWE@]

variance 2.88

 

[Anum96]

variance 2.88

For this part mean was 1 right?

 

[n.r.s.007]

For this part mean was 1 right?

Yeah it was 1

But in the question in the first part itself is has stated that J and S will be in taxi Q making the answer 15

What was the answer of 7b? They said about variable Y and then asked about variable X... quite confusing
There was no information about X

myu cancels out in that part.
Till I remember i found probablity of P(X < 1.5 or 1.2)

 

[The Sarcastic Retard]

316 days in part 7(i)?

what was the answer for conditional probability

 

[The Sarcastic Retard]

what was the answer for conditional probability

I dont remember, U temme urs, if I can remember that figure.

2/9 or 5/9, dont remember exactly

 

[The Sarcastic Retard]

2/9 or 5/9, dont remember exactly

Mine sh like that only.. I dont remember much.. It was like that only.. If m not wrong..

 

[Mahreen Mustafa]

I gave 5/9

 

[The Sarcastic Retard]

2/9 or 5/9, dont remember exactly

U are talking about that only na, positive even numbers sth?

 

[The Sarcastic Retard]

I gave 5/9

Mine was like this only 5/9

 

[Anum96]

Mine was like this only 5/9

Did you guys take into account zeros?
