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)?

(In reply to re(3): One Mean Poisson = Shark by Richard)

Richard queried: "But are there people who would copy a solution [as opposed to the original problem] from the internet without mentioning their source?

What's the difference, Dick ?
