Contamination problems in semiconductor manufacturing can result in a functional defect, a minor defect, or no defect in thefinal product. Suppose that, 21, 51 and 28% of the contamination problems result functional, minor and no defectsrespectively. Assume that the effects of 10 contamination problems are independent.Round your answers to four decimal places (e.g. 98.7654).(a) What is the probability that the 10 contamination problems result in two functional defects and five minor defects?(b) What is the expected number of contamination problems that result in no defects?(c) What is the standard deviation of the number of contamination problems that result in no defects?
