Discrete Random Variables
This chapter introduced some special discrete random variables, i.e. binomial random variable and Bernoulli random variable, Poisson random variable, negative binomial random variable, geometric random variable, and hypergeometric random variable. The formulae for the basic parameters of these special discrete random variables have been provided. In addition to the typical examples and problems such as the number of the typographical errors on a book page, and the ball withdrawal from an urn without replacement, one special problem that is related to acceptance sampling in quality control has also been presented.
