And so you say, oh, OK, Sal. I know the solution there. I just have to get more granular. Instead of dividing it into minutes, why don't I divide it into seconds? So the probability that I have k successes, instead of 60 intervals, I'll do 3,600 intervals. And so the probability of k successful seconds, so a second where a car is passing at that moment, out of 3,600 possible seconds, so that's 3,600, choose k, times the probability that a car passes in any given second. Well, that's the probability, that's the expected number of cars in an hour divided by number of seconds in an hour.
