A mechatronic assembly is subjected to a final functional test. Suppose that defects occur at random in these assembles, and that defects occur according to a Poisson distribution with parameter lambda = 0.06.
a. What is the probability that an assembly will have exactly one defect?
b. What is the probability that an assembly will have one or more defects?
c. Suppose that you improve the process so that the occurrence rate of defects is cut in half to lambda = 0.03.
What effect does this have on the probably that an assembly will have one or more defects?
