An insurance policy on an electrical device pays a benefit of $2850 if the device fails during the first year. The amount of the benefit decreases by $950 each successive year until it reaches 0 . If the device has not failed by the beginning of any given year, the probability of failure during that year is 0.29. Find the expected benefit under this policy?
