Determine whether the distribution is a discrete probability distribution. Is the distribution a discrete probability distribution? Why? Choose the correct answer below. O A. No, because some of the probabilities have values greater than 1 or less than 0. O B. Yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive. O C. Yes, because the distribution is symmetric. O D. No, because the total probability is not equal to 1. CH X P(x) 0 0.16 1 0.21 0.26 0.21 0.16 3 4
