Suppose that you feel that accidents along a particular stretch of highway occur rooghily according to a Poisson process and that the intensity of the process is either 2,3, or 4 atecldeter per week. Your prior probabilities for these three possible intensities are 0.25,0.45 and 0.20. respectively. If you observe the highway for a period of three weeks and 10 accidents occtir; what are your posterior probabilities?
