I'm a bit confused about the wording in this question, I started answering by putting E(N) = 0.1 and E(X) = 0.5 and working out the mean and var parameters for S the aggregate distribution, so I could then work out the lamda + cr = lamda * M(r)
How come it just uses X?
When would I have to calculate the parameters for S?
Can someone help please? Thanks
