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.
Fill in the required fields to see your result.
Probability
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.
