4. Monthly aggregate claims S are modeled by a compound Poisson dis- tribution where N has Poisson parameter 12 and a claim X takes the values (1,5, 10) with respective probabilities (0.2, 0.3, 0.5). Determine the probabilities P(Sr) for r≤200 and hence find the median, mode, 95 and 99th percentiles of S. What are the mean and variance of S?
