## Quick Answer

Solve discrete binomial probability distributions. Enter trials, success probability, and target successes to see PMF and cumulative results.

## Definition

A binomial distribution calculator is a probability tool that computes discrete probabilities for experiments with independent, binary outcomes. Given a number of trials (n), a success rate per trial (p), and target successes (k), it calculates the exact probability P(X = k) using the binomial formula. It also sums individual probabilities to yield cumulative results like P(X ≤ k) and standard statistics like mean and variance.

## How to Use

1. **Input trials** — Enter the total number of independent trials (n).
2. **Set success rate** — Input the probability of success on a single trial (p) as a decimal between 0 and 1.
3. **Set successes** — Enter the target number of successes (k) you want to analyze.
