A laptop assembly is subjected to a final functional test.Suppose that defects occur at random in these assemblies, and thatdefects occur according to a Poisson distribution with parameter λ=0.03.
- What is the probability that an assembly will have exactly onedefect?
- What is the probability that an assembly will have one or moredefects?
- What is the probability that an assembly will have no more thanthree defects?
- What is the probability that an assembly will have more thantwo defects?
- Suppose that you improve the process so that the occurrencerate of defects is cut in half to λ = 0.015. What effect does thishave on the probability that an assembly will have one or moredefects?
