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