#### Balls and Bins People

Now, there are nmtotal ways to throw m balls into n bins, and each throwing scheme either leave at least one bin empty or puts at least one ball in every bin, so there are then nm−n(n−1)mways to have at least one ball in every bin. Date: March 18, 2008. 1 Is this answer better?

#### 7.1 Randomized Load Balancing and Balls and Bins Problem

We can model this as tossing balls into bins. Here, balls can be considered as tasks and bins as resources. We discuss this problem ﬁrst, since it is a simple way of describing load balancing and is a nice and more comprehensible example to study. 7.1.1 Balls and Bins Consider the process of tossing m balls into n bins.

#### 7.1 Randomized Load Balancing and Balls and Bins Problem

Balls and Bins Consider the process of throwing m balls into n bins. Each ball is thrown into a uniformly random bin, independent of other balls, which implies that the probability that a ball falls into any given bin is 1/n. Based on this process, we can ask a variety of questions.
