So this would be the number of coin tosses times the probability of success over each toss. This is what we did with the binomial distribution. So maybe we can model our traffic situation something similar. This is the number of cars that pass in an hour. So maybe we could say lambda cars per hour is equal to, I don't know, let's make each experiment or each toss of the coin equal to whether a car passes in a given minute. So there's 60 minutes per hour. And then so there would be 60 trials.
