“How can we measure the probability of drawing something without replacement?”

Sometimes, we would like to know the probability of choosing certain types of cards and that we either choose the right or wrong card. The problem with this is that the probability will change with each card drawn. As a result, this will take on a special Hypergeometric Distribution.

The probability of choosing the desired card can be found with the equation

With N being the total population, n being the number of draws, K being the number of successful members of the population, and k being the amount of the successful members desired.
