MATHS 4024 PAPER 22

[Usman17]

I got 3/20 too... One was 1/20 the other 3/20... Can't remember others...

Yeah I got those answers too Yayyyy

it was 3/20 if sm1 says that its wrong and should be 5/37 or something else thn i can prove it

 

[iFuz]

my gradient was 8.8 and yhh
SALIM ARRIVED 9 MINS EARLIER.! INFACT I ASKED SALIM HE WAS SITTIN RIGHT BEHIND ME

 

[Silent Hunter]

yes..............................salim arrived first and 9 minute late was ravi

 

[examphobic]

Yeah it was something like that... I dont remember exactly...!!
That vector question was interesting had to use ur brains loll
What was the gradient coming in that graph question... Mine was 8...!

really? thank God i thought i was making sme mistake mine tooooo

 

[examphobic]

Salim arrived first and 9 minutes later his brother arrived.!!

corrct

i think you didnt read the qstn properly for the 2nd part it said that there wuold be replacement unlike the first part so the denominator would stay the same... im guessing you did it with the same method as the first part as i did it that way right now and i got 3/20 aswell .... dont worry i messed up with the very first part of taht qstn in which we had to give the prob. of N .. i didnt simplify the fraction

nd i guess u didnt read part Bz statement . it said that the blocks would be taken and NOT replaced. den part B)a) asked abt a words ratio.. maybe BAN dnt remember... den part B)b) said that the blocks WERE replaced i.e the blocks taken out in part B)a) were replaced not that there will be replacement ( take note of the english) and this process was repeated... AND AS IT CLEARLY STATED IN QUESTION Bz STATEMENT THAT THERE WILL BE NO REPLACEMENT ND THAT QUESTION WAS A PART OF IT SO 3/20 is correct .. get it?

I didnt get it :S It was a simple probability question yaar... U have confused me :O

i am sorry.. in short there was replacement... when they said the blocks were replaced it meant the blocks taken in A part were put back b4 the part B blocks

 

[examphobic]

@examphobic: U saved me from a heart attack...!!! THNX BUD!!!

u r MOST welcum

 

[examphobic]

and u saved me 4rm the gadient question tension

 

[abdullahaftab]

p1 was easyyyyyyyyyy

I am really sorry if this causes anyone any pain but if you guys think that the qstn meant that the block were just going to be replaced than my frnds you guys have got to maybe look at some of the past papers of mathematics and even maybe statistics ... whenever the qstn wants to tell us that a fresh new expirement is starting it will always state that clearly and never in any past paper is it written in the first part that blocks wont be REPLACED and in second part that block will be REplaced for this purpose ..... But then again we probably will never figure out who is right and whos wrong so i guess all we can do is pray for our results.. GOODLUCK ALL

Go ahead...... :lol: :lol: :lol: :lol: :lol: :lol:

 

[iFuz]

OH sure.!!

dude.. u were given 3 position at start of part b) that meant that u have to arrange tiles in that way.....
now if in part b) before part i) it was clearly stated that "WITHOUT ANY REPLACEMENT"... and that meant that it applies to both parts of b i.e. i and ii
now if u take out a tile and put it on postion 1 u'll simple calculate its probability and for 2nd place u need a tile that can only be possible if tile on postion 1 remains there
if u put in tile from position 1 than u'll not be able to complete the sequence
in part b. ii ) it was clearly written "THE SAME PROCESS WAS REPEATED"
so that meant that what we did in part b.i) that should apply here too... so if we are getting 1/20 there than here we should follow the same method.

the word replacement was to put back 3 tiles we already took because we want that 3 places free again to have another sequence ! and sequence is only possible if previous values are saved ...

so answer was 3/20

NEED SOMETHING MORE???? HOPE ITS CLEAR TO U NOW @LIKOSP

 

[iFuz]

what was ur answer to probability question?

 

[workaholic]

wat ws the ans to the surface area qst.... 1510 or not?

 

[likosp]

what was ur answer to probability question?

Dude it doesnt matter how much we both argue about this stuff at the end i think that both of us will believe that we have both done it correctly...

 

[iFuz]

ahahahahahahahahahahahahaha....
ok ok sure! lets wait for the marking scheme and hope for the best

 

[Silent Hunter]

u'll have to wait for august

 

[likosp]

ahahahahahahahahahahahahaha....
ok ok sure! lets wait for the marking scheme and hope for the best

Sure im surely going to PM you when i find out that im RIGHT WUHAHAHAHAH... jkjkjkj
GOODLUCK 4 RESULTS...
