The INVBINO() function returns the negative binomial distribution. The first parameter is the number of trials, the second parameter is the number of failures, and the third is the probability of failure. The number of trials should be larger than the number of failures and the probability should be smaller or equal to 1.
De funksje INVBINO () jout de negative binomiale ferdieling werom. De earste parameter jout it oantal kearen besykjen oan, de twadde it oantal mislearre kearen besykjen en de tredde de kâns op súkses. It oantal kearen besykje moat grutter wêze as it oantal mislearre kearen en de kâns (lykas elke kâns) moat grutter wêze as of gelyk oan 0 en lytser wêze as of gelyk oan 1 (dus yn it sletten ynterfal [0, 1] lizze). Feitlik is dit deselde funksje as BINO ().
