# On the German Tank / Taxicab Problem

I always get giddy when I can apply real statistics and math to problems in my life. Recently, I had an opportunity to apply the ‘Taxicab Problem’ to something that came up at work. Given that I work for a ridesharing platform and I was quite literally counting “taxis” (or at least cars meant to drive others around), this was doubly exquisite.

For the uninitiated, the Taxicab / Germany Tank problem is as follows:

*Viewing a city from the train, you see a taxi numbered x. Assuming taxicabs are consecutively numbered, how many taxicabs are in the city?*
