The number of cars entering a tunnel leading to an airport in a major city over a period of 200 peak hours was observed, and the following data were obtained. Find the empirical probability distribution for this experiment. (Round your answers to three decimal places.)

Number of Cars, x	Frequency of Occurrence	Probability
0 < x 200	19
200 < x 400	20
400 < x 600	36
600 < x 800	75
800 < x 1000	37
1000 < x	13
