The following data are the result of a historical study of the number of flaws found in a porcelain cup produced by a manufacturing firm. Use these data and the associated probabilities to compute the expected number of flaws and the standard deviation of flaws. Flaws Probability 0 0.448 1 0.292 2 0.136 3 0.086 4 0.038 (Round the intermediate values and final answers to 3 decimal places, eg. 0.215.) Expected number Standard deviation
