Response:
  • Question 47

    A series system whose reliability at 5 hours is 0.80, has three components with these historical constant failure rates:
    λ 1 = failure rate for component 1 = 0.04 failures/hour
    λ 2 = failure rate for component 2 = 0.07 failures/hour
    λ 3 = failure rate for component 3 = 0.01 failures/hour
    Three of the four answers are the three component reliabilities at 5 hours. Which is incorrect?
