Hypergeometric Probability Calculator

Calculate the exact probability of drawing exactly k successes from a finite population without replacement. Ideal for quality control sampling, card game odds, and any scenario where items are not returned to the pool after selection.

Hypergeometric Distribution Calculator

Calculates exact probabilities when drawing items from a finite population without replacement. Use it in quality control, card games, or any scenario where sampling changes remaining proportions.
