Decorative Candles. At a mart, decorative candles come in cartons that hold half a dozen candles. Experience indicates that 80% of the cartons have no damaged candles, 17.7% have one damaged candle, 2.2% have two damaged candles, and 0.1% have three damaged candles, and the percentage of cartons with four or more damaged candles is negligible. A candle selected at random from a carton is found to be damaged. What is the probability that this candle is the only damaged one in the carton?
