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 more than one work, in which case, as I said,
the number of works submitted per person would also have to be
figured into the equation somehow. Besides, if one person submits
ten pieces and another person submits 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 entries.

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 that
applied from this same institution, and only 3 got in, then the
calculation 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 1.5%
chance or is it a more complex formula?
Forgive the off topic request but it does relate to photo as 3
of our program got into a photo show and I want to be able to
mathematically brag about it to the dept. head/dean.
