Suppose dice had four sides instead of six, so rolling a single die would produce equally likely numbers from 1 to 4, and rolling two dice would produce numbers from 2 to 8. a. Compute the probability distribution of outcomes from rolling two dice. b. Calculate the mean, standard deviation, and coefficient of variation of the distribution.
