I am familiar with Binomial Distribution and know that it is used in the following scenario :-
In each individual test, the probability of A happening is p and not happening is 1-p. What is the probability of A happening exactly k times in n repeated tests?
C(n,k) * p^k * (1-p) ^ n-k
When a coin has tossed, it will show a head at 50% probability and a tail at 50% probability. What is the probability of getting two heads among four tosses?
Ans. C(4, 2) * (1/2) ^2 * (1/2) ^2 = 6/16 = 3/8
Can someone please explain what is Hypergeometric distribution and how do we use it? Please provide an example or a sample illustration.
