泊松分布
The number of defective components produced by a certain process follows
a Poisson distribution with mean k.Each defective component has probability p0 as being
repairable.
a.Find the probability that exactly N defective components are found.
b.Suppose we have exactly N defective components,let Y be the number of repairable
components,ˉnd the probability distribution of Y .
c.Find the moment generating function of the distribution you obtained in part b.
d.What is the probability that we ˉnd exactly N defective components,and among them,
n are repairable?
