At a border inspection station, vehicles arrive at the rate of 10 per hour in a Poisson distribution. For simplicity in this problem, assume that there is only one lane and one inspector, who can inspect vehicles at the rate of 15 per hour in an exponentially distributed fashion.
What is the probability (percentage) that when you arrive there will be three or more vehicles ahead of you? (Round your answer to 1 decimal place.)
