Probability
Normal Distribution Probability Calculator
Compute the cumulative probability P(X ≤ x) for a normal distribution with a given mean and standard deviation. Use it to find the percentage of a population below a test score, measurement threshold, or quality specification limit.

Probability
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.
