Determine whether the distribution is a discrete probability distribution. P(x) 0.25 1 0.30 2 - 0.10 3 0.30 4 0.25 Is the distribution a discrete probability distribution? Why? Choose the correct answer below. O A. Yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive. B. Yes, because the distribution is sym tric. C. No, because some of the probabilities have values greater than 1 or less than 0. D. No, because the total probability is not equal to 1.
