How to calculate the probability of this questions?(adsbygoogle = window.adsbygoogle || []).push({});

Supposed there are m bukcets, n balls. use function f(x) to decide which bucket the ball go. Supposed that the probability a ball going to 0-j is 0.9 and going to j -> m-1 is 0.1. What's the probability of for every bucket there is at least one ball?

I really get stuck.
