The time until failure for an electronic switch has an exponential distribution with an average time to failure of 4 years, so that λ = 1/4 = 0.25. (Round your answers to four decimal places.) (a)What is the probability that this type of switch fails before year 3? (b)What is the probability that this type of switch will fail after 5 years? (c) If two such switches are used in an appliance, what is the probability that neither switch fails before year 6?

Q3. Each time a machine is repaired it remains "up" for an exponentially distributed time with rate A. It then fails and "down", and its failure is either of two types. If it is a type 1 failure, then the time to repair the machine is exponential with rate μ!, if it is a type 2 failure, then the repair time is exponential with rate H2. Each failure is, independently of the time it took the machine to fail, a...

4.5. There are two common types of failure to a critical electronic element of some machinery: either component A or component B may fail. If either component fails, the machinery goes down. Component A fails according to a Poisson process with mean rate 1.1 failures per shift. (The company operates 24/7 using eight-hour shifts.) Component B fails according to a Poisson process with a mean rate of 1.2 failures per day (a) What is the probability that there will be...
