Negative binomial distribution probability calculation
Calculate the probability, accumulation probability and variance of the number of failures before the fixed number of successes are reached.

Calculation method and processing rules
The logarithmic gamma representation and normalization incomplete beta cumulative probability using the combined coefficients.
scope of use
Each test is independent, and the probability of success is constant; K only counts the number of failures, and does not count the total number of tests.
Will the input content be saved on the server?
This tool handles input in the browser, and does not upload files or form content. Typing practice scores are only saved in the native browser.
Why may the result be different from other tools?
Each test is independent, and the probability of success is constant; K only counts the number of failures, and does not count the total number of tests. Please compare the input unit, rounding method, applicable rules and data version first.
