If u think that way, I am damn sure ur thought process is very poor/mean.

Dude,forum is all about learning which including sharing our Gyan/knowledge.

Posting IMO( and that too wrong IMO in ur case) is nothing but BS!!

May be I am sounding harsh,but I really reconsider ur outlook and start posting great answers along with its explanations.

I mean its not necessary that ur name (girish) need to come in Hall of fame fo rthe best poster( like DanaJ/Logitech/Cramy) but users will certainly thank you wholeheartdely.AFTER ALL WE ALL say "luck" its nothing but accumulated good fortune u bring it by sharing "things".

Hope I helped u in one way or theother & i am eager to ee ur posts with fantastic explanations.

(E) [(p + q + r)C3 - pC3 - qC3 - rC3] + 1
(p + q + r)C3 are the total no of ways to choose three points.
of these pC3 are all the three point on line which form a st. line,
One straight line can be formed joining different points on the three parallel st. lines.

so IMO E

Thanks!
hey Hey girish,

I saw ur explanation bro..Seems I have sounded wrong...I was well aware that tone could give wrong connotations.See,this virtual way of telling things is damn tuf bro.

Girish,we are all in same boat as Sanju said.All want to go to ISB & IIM's and some to HSB & Stanford..(hopefully iam not aspirant for HSB..heheh becox i cant get in...)

bro, dont feel intimidated by others mockery..there are comedians who r there to make fuss of everything.
SO u just start posting...i am damn sure u can do the best for BTG!!

Any doubts..any moment we are here to reach u out...

I am proud of ur wrds & the humility u showed was too gud & i say U r awesome!!

I like people who are humble bro!!if i have sounded bit harsher .plz plz do consider my apologies..!

Hey Girish

Govind is a nice man and so is me I believe. The only difference between me and him is that a renowned mental asylum has issued me the certificate that I'm perfectly OK, which I can show to others as well, but Govind has not have got one to prove his mentality. (HOLI HAI sorry holi thi)

Let's discuss the main query now, please!!
