Alamp has two bulbs, each of a type with average lifetime 1700 hours. assuming that we can model the probability of failure of these bulbs by an exponential density function with mean μ = 1700, find the probability that both of the lamp's bulbs fail within 1800 hours. (round your answer to four decimal places.)
