c) An insurance, specializes in cell phone insurances. Meaning if the cell phone breaks down, they pay for replacement or repair. They only insure cell phones which have already been on the market for a while, so that the probability of breaking down is known. We assume there will be no recalls with these cell phones and that the probability to break down or average cost of repair is known. The insurance has a million customers. How does the formulas given in part a and b of this problem, allow the insurance to almost totally avoid any financial risk, by underwriting these insurances? (Meaning they are not at risk of suddenly lacking the money to pay for the insurance claims.)
