The number of cars which pass a certain intersection daily between 12:00 and 14:00, follows a homogeneous Poisson process with intensity λ = 40 per hour.  Among these there are 0.8% which disregard the STOP-sign.

What is the probability p≥1 that at least one car disregards the STOP-sign between 12:00 and 13:00?
