Question 1105513: an industrial process manufactures items that can be classified as either defective or not defective. the probability that an item is defective is 0.1. an experiment is conducted in which 5 items are drawn randomly from the process. let the random variable X be the number of defective in this sample of 5. What is the probability mass function of x?

The probability mass function of the binomial variable X is,
P%28X%29=C%285%2CX%29%2A%280.1%29%5EX%2A%281-0.1%29%5E%285-X%29
