Question: problem 4 an electrical device has two components a and...

Question details

Problem 4. An electrical device has two components, A and B. Each component can be good or can be in a shorted or open-mode failure state. Lets assume that component A has probability 0.6 of being good and probability 0.2 of being in each of the failure states, and that component B has probability 0.7 of being good. 0.2 of open failure, and 0.1 for shorted failure. Furthermore, we will assume that the two components function independently (a) What is the probability that at least ore of the components is shorted?
(b) What is the probability that neither is good? (c) If the two components are wired in series, what then is the probability that current can pass through? (d) If they are wired in parallel, what is the probability that current can pass through? Current can pass through a device if it is good or if it is in the shorted failure state.
