The probabilities of a machine manufacturing 0, 1, 2, 3, 4, or 5 defective parts in one day are 0.75, 0.17, 0.04, 0.025, 0.01, and 0.005, respectively. Find the variance and standard deviation of the probability distribution. 1. The number of computers sold per day at a local computer store, along with its corresponding probabilities, is shown in the table. Find the variance and standard deviation of the distribution. 2. Number of Computers Sold X Probability P(X) 0.1 0.2 2 0.3 3 0.2 0.2 4.
