Two parallel lines are crossed by a transversal. what is the value of x? x = 40 x = 70 x = 110 x = 130

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. 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

Which one is the correct answer, and why?
