In a certain production company, according to the test results from a motherboard 50% of board failures are caused by assembly defects, 30% by electrical components, and 20% by mechanical defects. Suppose that 10 boards fail independently. Consider that the number of assembly, electrical, and mechanical defects among the 10 boards are respectively denoted by the random variables X, Y, and Z. a. P(X=5,Y=3.2=2) b. PIX=8)= c. P[X=8|Y=1)= d. PX=7,Y=112=2)=

All electric circuit board failures can be classified into one of the following mutually exclusive and collectively exhaustive categories: assembly defects (40%), electrical component defects (35%), and mechanical defects (25%). Suppose ten boards fail independently, and let the random variables X, Y, and Z denote the number of each type of defect among the boards respectively. What is P{X=8,Z=1|Y=1}?
