The Hypergeometric Distribution

​
sample size n

number of marked balls k

total number of balls N
100
mean:

5.00
variance:

(-n+N)
(-1+N)N

If
n
balls are sampled without replacement from a bin containing
N
balls, of which
k
are marked, then the distribution of the number of marked balls in the sample follows a hypergeometric distribution.
