Why do people say there is modulo bias when using a random number generator? http://stackoverflow.com/questions/10984974/why-do-people-say-there-is-modulo-bias-when-using-a-random-number-generator 2 by calling rand 3 . However rand 3 does not produce the numbers between 0 and 2 with equal probability When rand returns 0 3.. 4 11 1 is 4 11 but 2 is 3 11. This does not generate the numbers between 0 and 2 with equal probability. Of course for small.. range this could skew the distribution biasing the smaller numbers. So when does rand n return a range of numbers from 0 to n 1..
