The housing foreclosure crisis has been particularly devastating in housing markets in much of the south and west United States, but even when analysis is restricted to relatively strong housing markets the numbers are staggering.

What is the probability that exactly 10 foreclosure auctions occurred during a randomly selected five-day week in 2015 in Chicago?
