Hypergeometric Distribution With the binomial distribution you sample with replacement and count the number of successes after a set number of trials. But what if you sample without replacement? Now the trials are no longer independent and we can no longer use the binomial to model this situation. We need to look for another type of distribution that will describe these problems.
Hypergeometric Distribution Given a population with N members. We are interested in an outcome that can be classified as a success or a failure. Let the probability of success in the population be p . Sample from this population without replacement of size n .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
