Assume that Y denotes the number of bacteria per cubic centimeter in a particular liquid and that Y has a Poisson distribution with parameter 2. Further assume that 2 varies from location to location and has an Exponential distribution with parameter ß, where ß is a positive integer. If we randomly select a location, what is the expected number of bacteria per cubic centimeter?
