We have a system that has 2 independent components. Both components must function in order for the system to function. The first component has 9 independent elements that each work with probability 0.92. If at least 6 of the elements are working then the first component will function. The second component has 6 independent elements that work with probability 0.85. If at least 4 of the elements are working then the second component will function. (a) What is the probability...

A system consists of two components. P(the 1st component functions in satisfactory manner during its design life)=0.75, P(at least one of the two components functions in satisfactory manner during its design life)=0.86, and P(both component functions in satisfactory manner during its design life)=0.65. given that the second component functions in a satisfactory manner throughout its design life, What is the probability that the first one does also?

The electrical system for an assembly line has four components arranged in two parallel subsystems as shown in the diagram below. Each of the four components (labeled 1, 2, 3, 4) are independent and each has a 10% chance of failure. Because the components are independent, the two subsystems (labeled A and B) are also independent. If one component in a subsystem fails, then the whole subsystem fails because the power cannot get through. However, because there are two subsystems,...

Please show your work. The answer is only for reference. You have two electrical components of two different kinds. The lifetime of the first kind is exponentially distributed with parameter .2 and the lifetime of the second kind is exponentially distributed with parameter .3. If the lifetimes of the two are independent, what is the probability that the first will fail before the second? Answer: .4

A device has two electronic components. Let ?1T1 be the lifetime of Component 1, and suppose ?1T1 has the exponential distribution with mean 5 years. Let ?2T2 be the lifetime of Component 2, and suppose ?2T2 has the exponential distribution with mean 4 years. Suppose ?1T1 and ?2T2 are independent of each other, and let ?=min(?1,?2)M=min(T1,T2) be the minimum of the two lifetimes. In other words, ?M is the first time one of the two components dies. a) For each...

Suppose that a certain system contains three components that function independently of each other and are connected in series, so that the system fails as soon as one of the components fails. Suppose that the length of life of the first component, X1, measured in hours, has an exponential distribution with parameter λ = 0.01; the length of life of the second component, X2, has an exponential distribution with parameter λ = 0.03; and the length of life of the...
