Cars on the road (Posted on 2004-04-09) Difficulty: 2 of 5
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)?

<SilverKnight made the mistake of not changing the phrase "constant default probability">

There are other words, too, like probability which works well with the fraction 609/625 (with no quotes, of course). But are there people who would copy a solution from the internet without mentioning their source?
