- Suppose the duration (in hours) of a certain valve is a random variableX with density function f(x) = 648x−4 for x > 6, and zero otherwise. What's the time expected life (in hours) of this valve?(a) A lamp has two bulbs, each of a type with average lifetime 1300 hours. Assuming that we can model the probability of failure of these bulbs by an exponential density function with mean ? = 1300, find the probability that both of the lamp's bulbs fail within 1500 hours. (Round your answer to four decimal places.) (b) 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 two bulbs fail within a total of 1500 hours. (Round your answer to four decimal places.)Suppose a college professor never finishes her lecture before the end of the class period, and always finishes within five minutes after the class period is supposed to end.
