b. {(3,21), (5, -11), (15,20), (3,4)}

c. {(9, -11), (5, -8), (21,1), (7, -4)}

d. {(19, -7), (10, -3), (1,7), (19,17)}

e. {(7,12), (11, 5), (14,12), (6, -1)}

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
