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?

8. An HP laser printer is advertised to print text documents at a speed of 18 ppm (pages per minute). The manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.57 ppm and a standard deviation of 3 ppm. A Brother brand printer can print an average of 17.21 ppm and a standard deviation of 4 pages and its printer speed is also normally distributed. You select 10 of each printer at random. What is the probability that mean Brother print speed is at least 2 pages faster than the mean HP print speed?
