Last Question of Exam 2?

[BubbleWrapMan]

I was rank 2 in my cohort... just

[fitzm11]

yeh i also got the k is greater than or equal to root thing, was the second last one 1/4?

I got 1/4

yep i got 1/4
and i think im smart..

woahhh that last page may not have been such a fail, what did you get for the last probability one with machine A?

[BubbleWrapMan]

0.4103

[fitzm11]

0.4103

did you work it out using given that? hopefully i'll get method marks cause i just didn't know what the intersection would be and so resorted to assuming they were independent events

[naomizz]

can someone please explain how you got k=1/4 for the second last question of the tasmania jones question?

[BubbleWrapMan]

Yeah I did. I'm not really sure about it though.

I worked out that the intersection was the event of a dark chocolate from machine A, which is 1/2 x 1/2 = 1/4. But yeah I'm not completely sure.

0.4103

yay! It looked so wrong, I kept thinking maybe I needed to times or divide something by 2, but then I would get 0.8xxxx, thank god I didn't!!

[BubbleWrapMan]

It makes sense to be less than 0.5, since more of the B chocolates were darker (median was 4?)

derive T,

sub in x=1

equal it to 0.

0.4103 is correct, i confirmed with Paulsterio who will probs get a 50 even though he got 1 mc wrong

Can anyone remember the fraction that .4103 was equal to?
If I see that i'll know if I got it right but I can't remember what I had to 4dp

edit: 16/39 I think I had that

[ttn]

16/39

Yeh something a lot of us should be doing right now. Why did they have to put it in the middle block, it ruins my studying for spesh. I suppose its better than the 3:00 pm start for spesh 2
