MTG Hypergeometric Calculator

The hypergeometric MTG calculator can describe the likelihood of any number of successes when drawing from a deck of Magic cards. It takes into account the fact that each draw decreases the size of your library by one, and therefore the probability of success changes on each draw.

Population Size
Cards in your deck / library you are drawing from

Sample Size
Number of cards we are drawing ex. cards in opening hand

Successes in population
Number of cards you want that is in the deck / library

Successes in Sample
Number of wanted cards you want to draw
