help me either question 9 and 10 I have 20mins left

9. [10 points] The manufacturing of vinyl records has a three-step process, label prep, pressing, and trimming. The individual reliability of the three steps is 0.98,0.99, and 0.95 . a. What is the reliability of the vinyl record manufacturing process? Show calculations. b. After a revision of the manufacturing procedure, the reliability of the trimming step was increased to 0.97 . The other reliability was unchanged. What is the new reliability of the process? Show calculations. c. What is the percent improvement in reliability after the revision? Show calculations. 10. [10 points] Determine the total system reliability of the diagram given below. The individual component reliabilities are: A=0.85,B=0.83,C=0.90,D=0.87,E=0.97. (Hint: This is a series system with two component pairs in parallel.)
