) A lamp has two bulbs, each of a type with average lifetime 1,300 hours. Assuming that we can model the probability of failure of a bulb by an exponential densit probability that both of the lamp's bulbs fail within 1,000 hours. (Round your answer to four decimal places.) ) Another lamp has just one bulb of the same type as in part (a). If one bulb burns out and is replaced by a bulb of the same type, find the probability that the tw (Round your answer to four decimal places.)
