Question
Suppose that a day's production of 850 manufactured parts contains 50 parts that do not con-
form 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.
What is the cumulative distribution function of X?
The question can be answered by first finding the probability mass function of X.
