When two fair, six-sided number cubes are used, the probability of rolling doubles is 1/6. Suppose that Sydney is playing a game with two six-sided number cubes in which she rolls them a total of three times per play. What will be the mean and standard deviation of the number of doubles in a randomly selected play? A. mean = 0.17, standard deviation = 0.50 B. mean = 0.50, standard deviation = 0.42 C. mean = 0.50, standard deviation = 0.65 D. mean = 3, standard deviation = 0.42 E. mean = 3, standard deviation = 0.65
