In a short string of holiday lights, when at least one bulb in the string stops working then all of the lights go out. Assume that each bulb works or fails independently of the other bulbs, and suppose that each bulb has a 98% chance of working throughout the holiday season. On a string of eight bulbs, what is the probability that all eight lights work throughout the holiday season so that the string stays lit throughout the season?
