Distribution Calculator
Compute probabilities and quantiles for normal and binomial distributions, with a density curve.
About this tool
Distribution Calculator is a free online tool. Compute probabilities and quantiles for normal and binomial distributions.
Select the type of probability distribution (normal distribution, binomial distribution, Poisson distribution, uniform distribution, exponential distribution, etc.), enter parameters (such as the mean and standard deviation of the normal distribution), and the tool calculates the probability density, cumulative probability (P (X & x)), or quantile for the specified value.
Normal distribution: Enter μ and Sigma to calculate the Z-score and corresponding probability. Binomial distribution: Enter n and p, and accurately calculate the probability of success k times. Poisson distribution: Enter parameters and calculate the probability of an event occurring k times.
The tool draws probability density function (PDF) and cumulative distribution function (EDF) images and highlights the calculation area with color. Suitable for statistical learning, quality control, risk assessment and other scenarios.
The probability distribution calculator supports normal distributions, binomial distributions, Poisson distributions, etc., and calculates probability densities, cumulative probabilities, and quantiles.
