comment determining the size of a test bank given acceptable number of repeats
thanks a lot for this.. the numerator is somewhat tricky for me to understand. so lets say that there are 5 repeats. would it be choose(n , 5) * choose(n-5, 3) * choose(n-8,3) ? thanks!

with replacement, yea. so if you answer question 1, very unlikely (less than 5% chance) that the other 39 questions can be the same as question 1 from X. Sorry I forgot to add the less than 5% chance.
