For an extra $49 you can buy extended warranty protection on your new HDTV for three years. If the set requires maintenance during that lime, it will be free You estimate that there is a 5% chance that you might need a$300 repair within three years and a 1% chance that you will need a $500 repair, but the chances arc 94% that you will need no repair at all. Based on expected values, should you purchase the extended coverage?
