The manager of a baseball team has determined the number of walks, x, issued in a game by one of the pitchers. The probability distribution for x is as follows: P(x) 1/20 X 1 2/20 2 3/20 3 11/20 4 3/20 a) Is this a correct probability distribution? Why or why not? b) Calculate the mean (expected value) for x. c) Construct the probability distribution histogram for the number of 'walks'.
