Problem Statement
There are balls and bins that can fit arbitrarily many balls. All of the balls are then placed independently and at random into the bins. Estimate how many bins, on average, are empty. (Estimate the expected number of empty bins. In other words, if this were done over and over again, how many bins would be empty on average?) Your estimate must be an integer, or you will receive a score of zero.
