In a lot of 200 electrical fuses, 20 are known to be nonconforming. A sample of 10 fuses is selected.
(a) What is the probability distribution of the number of nonconforming fuses in the sample? What are its mean and standard deviation?
(b) Using the binomial distribution as an approximation to the hypergeometric, find the probability of getting 2 nonconforming fuses. What is the probability of getting at most 2 nonconforming fuses?

*************[[[[[[[[[[[[[[Solve parts a,b and c using Poissons distribution as an approximation of Binomial distribution]]]]]]]]]]]]]]************* Samples of 20 parts from a metal punching process are selected every hour. Typically, 1% of the parts require rework. Let X denote the number of parts in the sample of 20 that require rework. A process problem is suspected if X exceeds its mean by more than 3 standard deviations. (a) If the percentage of parts that require rework remains at 1%, what is the...
