Re: Hypogeometric using binomial approx word problem

Whee! My probability final's done! Most of you are probably sighing
in relief, no more pesky newbie questions from me.

I'm sorry, this problem actually has 7 parts to it and the first one is
the easiest one which asks for exactly 3 ppl is what I posted to here.
I had cut and pasted the problem from my word processor and somehow,
something was deleted (I'll blame the cat, yea yea, never the
operator's fault!) I..meant to do it, it... was a test! (just
kidding, it was an honest mistake.)

I looked up the answer in the book again, and the answer, 0.346, is to
part b which asks for at most 3. The correct answer is 0.253 for
exactly 3. I'm impressed by ***'s and Professor's Vickson's very
astute observations and efforts to figuring out what it really meant on
what the answer I gave really meant. :)

Anyways, guys, I'm gonna miss this forum.

Have a good xmas!

P.S. Maple eh? I gather that's a Matlab type of math oriented
application. I'm going to have to look that up one day.

So, P{N=3} = 0.2529, p{N >=3} = 0.9067. Similarly, P{n>3} = 0.6539 and
P{n<3} = 0.09325. None of these figures resemble the book's value.P(N<=3)=0.3461
