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. So just finishing up with our binomial distribution, n moments choose k successes times the probability of success. What's the probability of success? We said if this is, so this would be n, what's p equal to?
