In system 2 assume that the valves are A, B, & C.
It does not fail: .
You are evaluating 2 systems for a company. System 1 has 4 valves in sequence. If one fails, the system fails. The probability a value will fail is .01(1%)(assume independence)
What is the probability system 1 will not fail?
System 2 has 3 values. The probability a valve will fail is .4(40%)(assume independence).BUT in system 2, as long as one of the values does not fail, the system will not fail.
What is the probability that system 2 will not fail?
What is the probability that system 2 will fail?
I tried using various numbers using the Bayes Theorem and tried to put actual numbers, but could not the right answer.
Thanks,
