The complete question is:
A certain company produces 10,000 tables per year in a three-step process. The three steps in the process employ machines with the reliabilities listed here:
Step A - 0.987 Step B – 0.979 Step C – 0.915
Answer:
New reliability= 0.9593 ~ 0.959
Explanation:
Reliability is used in manufacturing process to ensure that a process produces the same level of output consistently. A process is reliable if it achieves the same results everytime.
Reliability can be applied to individuals, data, processes, and products.
In this instance we are to calculate the new reliability of the backup system.
Reliability of step C is 0.915
New reliability= 1 - (1- 0.915)^2
New reliability= 0.992775
Multiply this value by the reliability in step A and B to get system reliability
System reliability= 0.992775 * 0.987 * 0.979
System reliability= 0.9593
