Introductory Example Supposes that a day s production of 850 manufacturing parts contains 50 parts that do not conform to customer requirements. Two parts are selected at random, without replacement, from the batch. Let the random variable X equal the number of nonconforming parts in the sample. This case can be generalized as following in next slide 4 What are all possible value of X, and what are the associated probabilities.
3-1 Discrete Random Variables Many physical systems can be modeled by the same or similar random experiments and random variables. The distribution of the random variables involved in each of these common systems can be analyzed, and the results of the analysis can be used in different applications and examples. So instead of using the sample space of the random experiment we describe the distribution of a particular random variable . 5
