The first parameter is the number of trials, the second parameter is the number of successes, and the third is the probability of success. The number of trials should be greater than the number of successes and the probability should be smaller or equal to 1.
De earste parameter is it aantal kearen besykjen, de twadde is it oantal slagge kearen en de tredde is de kâns op súkses. It oantal kearen besykjen moat grutter wêze as it oantal kearen mei súkses en de súkseskâns (lykas elke kâns) moat grutter wêze as of gelyk oan 0 en lytser wêze as of gelyk oan 1 (moat dus yn it sletten ynterfal [0, 1] sitte).
