A product has five component is series, as follows:
A--B--C--D--E
The reliability of components A,B,C and D are as follows:
A. 0.92
B. 0.88
C. 0.85
D. 0.80
The product is required to have an overall reliability of 60%. What must the reliability of component E be in order to satisfy the requirement? If it is not possible to satisfy 60% reliability, what is the best reliability possible for the product and what would the reliability of component E be to satisfy this reliability?
