A rural highway has one lane in each direction. In one direction V = 300 veh/hr/ln at a railroadcrossing. The barriers at this crossing are lowered to block vehicles for four minutes and 30seconds for a train to pass. What is the probability that when the barrier is lifted, the queue hasexactly nine vehicles? Assume no initial queue.

Solution- Givenv = 300Since the likelihood is based on the number of vehicles, we may use the…
