One component has an error rate λ = 10-5 h-1 a) What is the probability that this component will still work after 5 years of operation? b) When 4 such components work together in a circuit. How big is the probability that the circuit will still work after 5 years of operation if the follwing: I. The components have serial function? II. The components have parallel function? c) to further increase the reliability of the circuit. What value must be λ if the reliability after 5 years of operation with serial function should be R = 0.9?

Please Use your keyboard (Don't use handwriting) Stat (3) One-half percent of the population has CORONA Virus. There is a test to detect CORONA. A positive test result is supposed to mean that you have CORONA but the test is not perfect. For people with CORONA, the test misses the diagnosis 2% of the times. And for the people without CORONA, the test incorrectly tells 3% of them that they have CORONA. (i) What is the probability that a person...

2. Consider the reliability model given in Assignment 5 Problem 1. You have discovered that the reliabilities given there were just rough estimates. After careful analysis of historical data, you know that each component has a random time until failure that is distributed according to the following table. Ideally, this machine shop should run for the next 2 years without the need to replace any components. Mean time until failure (MTTF); Time until failure (TTF) Component Distribution Exponential Parameters MTTF:...

The number of flaws x on an electroplated automobile grill is known to have the following probability mass function: p(0) = 0.6; p(1) = 0.2; p(2) = 0.1; p(3) = 0.1 a) Is this random variable continuous or discrete? Justify your answer. b) Verify that this is a proper mass function c) What is the probability that a randomly selected grill has fewer than 2 flaws? Calculate the probability, and use proper probability notation. d) What is the probability that...

1. A salesperson has successes on 2 out of 10 cold calls. What is the probability of getting 3 successes in 9 cold calls? 2. If the probability of success on a cold call is .20, and 500 cold calls are made, what is the probability of less than 84.5 successes? (use normal distribution to approximate the binomial, so need mean = np and st.dev = sqrt(npq) ) 3. In the past, the probability of success of a cold call...

Western Components, Inc. manufactures a variety of pinions,
gears and other component parts used by companies around the world.
Their major customer is a large west-coast aircraft manufacturer.
Currently, Western has substantial unused capacity due to a
downturn in production for this major customer. This in turn has
caused a significant drop in profits at Western since their workers
are highly skilled and Western does not want to reduce head-count
during this downturn which they expect to be temporary. Sally...
