Question

Suppose we toss m (numbered) balls into n (numbered) bins randomly.
Let X be the number of empty bins.
In class we showed that E(X) = n(1 − 1/n)^m. For n = 10 and m = 5, 10, 20 calculate E(X).
For the case n = 10 and m = 20, interpret the result for E(X) (write one sentence in English to explain what the result means).
