An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.97. 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 mean and variance of x. round your answers to three decimal places (e. g. 98.765). mean = variance =
