Step 1
The mean (also known as the expected value) is calculated as the sum of the product of each value and its corresponding probability. In this case, we have: Mean = (1 * 0.13) + (2 * 0.18) + (3 * 0.22) + (4 * 0.47) Now, let's calculate the mean: Mean = 0.13 + Show more…

Calculate the mean, the variance, and the standard deviation of the following discrete probability distribution. (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places. Round your final answers to 2 decimal places.) x -39 -20 -9 -6 P(X = x) 0.56 0.22 0.16 0.06 Mean = Variance = Standard Deviation =
