How does the Negative Binomial Calculator work?

r = target successes, p = success probability Then: Mean = r/p, Variance = r(1-p)/p² Then: Counts trials until r successes Then: Extends binomial (which counts successes in n trials).

Can you give an example of how to use the Negative Binomial Calculator?

Example: Input r=5, p=0.5 gives a result of E(X)=5.

Is the Negative Binomial Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Negative Binomial Calculator?

Our Negative Binomial Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.
