Twenty five heat lamps are connected in a greenhouse so, that when one lamp fails, another takes over immediately (only one lamp is turned on at any time.) The lamps operate independently, each with mean lifetime of 50 hours, and standard deviation of 4 hours. If the greenhouse is not checked for 1300 hours after the lamp system is turned on, what is the probability, that a lamp will be burning at the end of the 1300-hour period?
