Is the solution method correct given below ?
P(A to fail) =0.1
P(B to fail) =.05
The system fails if any of the two A or B fails,, find the probability that A has failed when system fails given that only one component has failed ??
P(A') + P(B') =1 since system has failed and only one component must fail
P(B') = 1/2 * P(A')
=> P(A') + 1/2 * P(A') =1
=> P(A') = 2/3
Please help as i have done this in the exam,, i know the answer is correct but instructor has given me zero marks so as an evidence i must show this to him ......
