1. 6x + 2y = -12 4x + 3y = 7

2. 4x - y = 26
5x - 4y = 8

3. 5x + 3y = 13
17x + 8y = -16

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
