An optical inspection system is used to distinguish among different part types. The probability of a correct classification of any part is 0.95. Suppose that three parts are inspected and that the classifications are independent. Let the random variable X denote the number of parts that are correctly classified. Determine the probability mass function of X. Round your answers to four decimal places (e.g. 98.7654). x f(x) 0   1   2     3   please explain me easy way please thanks.
