【Abstract】 In this paper,we discuss the risk model when the number of premiumincome and the premium are random variables.we prove the formla and the Lundberg inequality of ruin probability.As an application,we give the formla of ruin probability for the case of exponential distrbution.These results extend greatly the corresponding ones in the references.更多还原
