The limit as n approaches infinity of n choose k. We're going to have k moments in time, right? Because as n approaches infinity, these intervals become super, super, duper small, right? So these become moments in time. So we're going to have close to an infinite number of moments, and this is the number of successful moments where cars pass. If we have three moments where there was a success where a car passed, then we had a total of three cars pass, right? Or seven cars. Seven moments where it was true that a car passed, then we would have a total of seven cars pass in the hour.
