Dear Friends,

I sent the following to the multilevel listserv, but thought that some of you might actually have code to compute this in R.  If you do, please let me know.

I have an odd question. I am trying to compute the probability of drawing 120 teachers from a sample of 2000 teachers in 400 schools where no two teachers work at the same school. Assume that there are 5 teachers at each school, evenly spread. I was trying to do this with an "n choose k" type
situation, but I can't figure out how to include the part about only 5 teachers can be at any given school. Any ideas? I am not stratifying on school, just sampling teachers.

Thanks,

Kyle
