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 0,1,2,3,4 Probability 0.458, 0.283, 0.139, 0.082, 0.038

(Round the intermediate values and final answers to 3 decimal places.)

Expected number =

Standard deviation =
