And then so there would be 60 trials. And then the probability that we have success in each of those trials, if we model this as a binomial distribution, would be lambda over 60 cars per minute. And this would be a probability. This would be n. And this would be the probability. If we said that this is a binomial distribution. And this probably wouldn't be that bad of an approximation. If you actually then said, oh, this is a binomial distribution, so the probability that our random variable equals some given value k, the probability that exactly three cars pass in a given hour, it would then be equal to n. So n would be 60.
