That is called the probability of ruin, for the claim amount is supposed to be a combination of exponential distribution. We assume that the claim number distribution is Poisson and the waiting time distribution of the claim is exponential. In this paper, we determine the ruin probability for the claim amount, assuming that it is a combination of exponential distribution, which is called combination of exponential methodothercombination of exponential distributionexponential distributionpoisson distributionruin probabilityOther
