Subject: Confidence Level of Reliability Calculation
Message:
For example, there are tow components in a certain circuit. The failure rate for each of the components are given with a confidence level. One is 40 FITs, the confidence level is 80%, and another one is 15 FITs, the confidence lever is 60%. When I sum the failure rates of these tow components up to calculate the reliability of the circuit, what is the confidence level for the result?
