Let X denote the number of spots on a single throw of a fair 6-sided die. Find the mean, variance, and standard deviation of X. If you can, relate the mean and variance to the mean and variance. the possible values on this die is 1, 2, 3, 4, 5, 6. So what would be the probabilities for each of these values if it is a fair die? Put this into a table then find the mean and variance. Compare these to the mean and variance for a sum of two dice.
