question 12

Multiple Choice

Which of the following is a valid formula to compute the reliability of two components in parallel? In the pdf,the formula is different
Rs = (1^st component) + [(2^nd component) x (1 - 1^st component) ]
Not sure if I am missing anything?

• A)(Reliability of 1^st component)- (Reliability of 2^nd Component)(1 - Reliability of 1^st Component)
• B)1 - (1 - Reliability of 1^st Component)(1 - Reliability of 2^nd Component)
• C)(1 - Reliability of 1^st Component)(1 - Reliability of 2^nd Component)
• D)(Reliability of 1^st component)+ (Reliability of 1^st Component)(1 - Reliability of 2^nd Component)
• E)(Reliability of 1^st component)(Reliability of 2^nd Component)+ (Reliability of 1^st Component)(1 -Reliability of 1^st Component)
