If the probability of observing a car (read: at least one car) in 20 minutes on a highway is 609/625, what is the probability of observing a car (read: at least one) in 5 minutes (assuming constant default probability)?
...sorry, I can never resist a good pun. I am sorry to note that nobody picked up on my "cars run over dogs" reference.....
