Introduction

Learning Objectives:

  • Model random allocation problems
  • Analyze occupancy distributions
  • Apply to hashing and load balancing

Balls in Bins

Throw nn balls randomly into mm bins. Questions:

  • How many empty bins?
  • Maximum bin occupancy?
  • Birthday problem connection

Expected empty bins: m(1−1/m)napproxme−n/mm(1 - 1/m)^n approx me^{-n/m}

Applications

Apply these concepts to solve real-world problems in probability and statistics.

python
import numpy as np
import matplotlib.pyplot as plt

# Example implementation
print("Apply concepts from Balls in Bins and Occupancy Problems")
