Consider the standard balls and bins process. A collection of m identical balls are thrown into n bins: each ball is thrown independently into a bin chosen uniformly at random.

(a) What is the (precise) probability that a particular bin i contains exactly k balls at the end of the experiment?

(b) Suppose m = n. Let Y be the number of bins that are empty. What is the expectation of Y?

(c) What is the variance of Y?

Explain your calculations when you derive the bounds.
