Consider a game in which a red die and a blue die are rolled. Let x_R denote the value showing on the uppermost face of the red die, and define x_B similarly for the blue die.

a. The probability distribution of x_R is

Find the mean, variance, and standard deviation of x_R.

b. What are the values of the mean, variance, and standard deviation of x_B? You should be able to answer this question without doing any additional calculations.
