after first day :
d1 birds tagged
N-d1 birds not tagged
Probability that out of d2 birds captured D are already tagged
= (select D tagged birds out d1 tagged birds)*(select (d2-D) non tagged birds out (N-d1) non tagged birds) / (select d2 birds out of N birds)
= P(D | d1,d2,N) = [ (d1CD) * (N-d1)C(d2-D) ] / (NCd2)
{ nCx = n! / (x! * (n-x)!) }
P(D | d1,d2,N) = [ (d1CD) * (N-d1)C(d2-D) ] / (NCd2)

The sizes of animal populations are often estimated by using a capture-tag-recapture method. In this method k animals are captured, tagged, and then released into the population. Some time later n animals are captured, and Y, the number of tagged animals anong the n, is noted. The probabilities associated with Y are a function of N, the number of animals in the population, so the observed value of Y contains information on this unknown N. Suppose that k 4 animals...

Recall that Benford's Law claims that numbers chosen from very
large data files tend to have "1" as the first nonzero digit
disproportionately often. In fact, research has shown that if you
randomly draw a number from a very large data file, the probability
of getting a number with "1" as the leading digit is about 0.301.
Now suppose you are an auditor for a very large corporation. The
revenue report involves millions of numbers in a large computer

Selecting a random sample is an example of a statistical experiment, and the sample statistic p is a numerical description of the result of the experiment. Therefore, p is a random variable. The probability distribution of p is called the sampling distribution of p In practice, you select one random sample and use the information from that sample to estimate the population parameter of interest. However statisticians sometimes perform a procedure called repeated sampling, in which the experiment is run...
