Re: math question verrrrrry off topic
I taught Philosophy for 32 years in a Junior College; heard them all.
I believe you. :) Had a student who came to me in similar
circumstances, except he had the wrong teacher; he thought I was the
Phys Ed teacher.

Hmm, I thought that's what we all already have said, isn't it?
That that theoretical probability (1/4x1/4x1/4) would hold only if
assumptions were met, and since assumptions are obviously not met
(for example, judging is not a random lottery of course
but is done
on the basis of criteria, arbitrary or otherwise but certainly not
random). Also, no one has said whether the 600 entries
are 600 works
or 600 people; I was assuming that they are 600 works representing
fewer than 600 people, in other words people could submit
one work, in which case, as I said, the number of works
person would also have to be figured into the equation somehow.
Besides, if one person submits ten pieces and another
one, the ten pieces by the one person couldn't be considered
independent entries in the same way one of those ten could be
considered independent of the one from the other person, and
independence is also an assumption that must be met in order to
consider the probability of acceptance to be the same for all

Okay, Chris. Here is it-- straight from my resident statistician
If they were the only 3 people from that institution who applied,
AND if judging was completely random, then the
probability of this
is roughly 1 in 64 (key word: roughly). If more than
from this same institution, and only 3 got in, then the
will be more complex.
Hope that helps. :)

OK for you math people (Yves?): If there is a show and 600
entries, and 150 are accepted, there is a 1 in 4 chance of
acceptance. If 3 people from the same institution are accepted
what percent chance is that--is it 1/4 x 1/4 x 1/4 or a
or is it a more complex formula?
