My Mail StationeryDear Allstats,
I am faced with yet another difficult problem in probability. Any help would
be appreciated.
1)From a lot of N distinct articles, articles are selected at random and
with replacements. What is the expected number of drawings necessary to get
n distinct items, and what is its variance?
2)In the preceding problem, what would be the mean and variance of the
number of drawings needed to get n specified articles?
