[SOLVED] failure of a system of components logically arranged in series and parallel The performance of the valves in (V1 OR V2 OR V3) AND V4 AND V5 has been assessed in more detail under conditions closer to those experienced in-service and the distribution functions of the random time to...

Thanks, With your advise, I have got the solution to the problem. I think that the problem must have been stated wrongly.

[SOLVED] Failure probability [b]1. Homework Statement [/b The performance of the valves in Q5 has been assessed in more detail under conditions closer to those experienced in-service and the distribution functions of the random time to failure have been quantified. The useful life period...

My attempts to solve the problem It is F = AUBU(CUD) I had derived the below using the associative law. But after plugging in the values of A,B,C and D , my answer were still different from the given answer. P(A) +P(B) +P(CUD)-P[A]P[B]-P[A]P[CUD]-P[B]P[CUD]+P[A]P[B]P[CUD]

[SOLVED] probability of failure The performance of the valves in Q5 has been assessed in more detail under conditions closer to those experienced in-service and the distribution functions of the random time to failure have been quantified. The useful life period, prior to wear-out, occurs...

[SOLVED] Bolean Algebra Question The failure of a subsea compressor system is described by the following Boolean Algebra statement: F = A UBU(CUD) If P[A] = 0.01; P[B] = 0.0034; P[C] = 0.00067; P[D] = 0.002, calculate the probability P[F] given independence between A,B,C,D...
