a) binomial distribution.
b) poisson distribution.
c) hypergeometric distribution.
d) none of the above

c) hypergeometric distribution.

Explanation:

Hypergeometric distribution -

It is the distribution curve of the " k " success probability in " n " draws , without any replacement with the size of " N " , having " K "  , objects .

This distribution is used to calculate the statistical significance for " k " success out of " n " draws .

This required to detect the which sub - population are under or over represented in a sample .

Hence , the probability distribution given in the question is of , hypergeometric distribution .
