I have told you the minimum marks that I expect, I desperately want an A*It dpends on the gt bro but an a for sure
Me 2 lets hope we get it!I have told you the minimum marks that I expect, I desperately want an A*
ummm... i think 34 ot 36littlecloud11 syed1995 MustafaMotani daredevil and others please post GT acording to you
mine is around 37 +-1
tat was part c
i never liked nCr methodi did that part with nCr /............ total were 12 and there were 5 chocolates ....so i took the probability of 0 choco,then 1 and so on .....dont know if i have done it correctly or not
but was there any possibility to do the question by that method ???????? cz i think i have lost all marks in q7.......may be some working marks will be awardedi never liked nCr method
me too!i did that part with nCr /............ total were 12 and there were 5 chocolates ....so i took the probability of 0 choco,then 1 and so on .....dont know if i have done it correctly or not
tioned in the question dat each tree of a specie was differentHow many of you considered the trees of a particular type identical. For example for part ii i said that no. of arrangements was 3! because the arrangements of the trees within each block is not important after all the hibiscus trees are not different. they are identical. If cie really wanted us to think that trees of a particular species are different then they are out of their minds. They could have given a better example which wasn't so confusing.....
That's what happened to me too! Every step was perfect but the answer is fluctuating a tad. I'm hoping I'd get 2 out of 4 atleast, for finding np and npq AND setting the k/9 probabily.GUYS I USED 96=np and 32= np(1-p) ! but still i calculated the value wrongly will i be awarded any marks ? p.s this is my only mistake i hope ! -_-
when u got the value of n incorrect then how u got k correctThat's what happened to me too! Every step was perfect but the answer is fluctuating a tad. I'm hoping I'd get 2 out of 4 atleast, for finding np and npq AND setting the k/9 probabily.
if u would have the courtousy to look in previous answers some one perhaps little cloud wrote themwhen u got the value of n incorrect then how u got k correct
and what about that last question
I wish I knew, it's kind of funny.when u got the value of n incorrect then how u got k correct

Oh I messed up, I thought it was about toffees drawn from Ahmed's bag. I set the table for 0, 1, 2, 3,4 and 5. Got it right at the last moment, heh. Alhumdulillah! xD
Did you get it right baad main?i also did the same .......
Did you get it right baad main?
Yes u are right. Because it said all the hibiscus trees had to be separated. If u calculated the arrangements for them to be together and subtracted it from total it would also involve those arrangements in which two hibiscus trees or three hibiscus tree is together.Q6 iii) it was 8!x9P4 not 12!-(9!x4!)
In the last part didn't they mean that no two (or more) hibiscus plants could be together?Total trees 15.
Hibiscus:4, Oleander: 2 J-something: 9
(i) selection of 12 trees where there has to be a minimum of two of each kind.
A: 2O, 2H, 8J = 2C2*4C2*9C8 = 54
2O,3H, 7J = 2C2*4C3*9C7 = 144
2O, 4H, 6J =2C2* 4C4*9C6= 84
total = 54+144+ 84 =282
(ii) The company picks 6J, 4H and 2O. How can they be arranged if the trees of the same type are are kept together.
A: 3!*4!*6!*2!= 207360
(iii) Arrange the 12 trees so that the hibiscus plants are not together.
A 12! -(9!*4!)
