Frequently Asked Questions
A binomial distribution describes the number of successes in a fixed number of independent Bernoulli trials, each with the same probability of success.
The result is the probability of observing exactly k successes (exact), at most k successes (cumulative), or between k1 and k2 successes (range), given n trials and success probability p.
The calculator validates inputs and shows inline error messages. Ensure n is a non-negative integer, p is between 0 and 1, and k values are non-negative integers within range.
