Determine whether the table gives the probability distribution of the random variable X. Explain your answer. x −1 0 1 2 3 P(X = x) 0.3 0.1 0.2 0.2 0.2 A. Yes, because the probabilities are all between 0 and 1, inclusive, and the values are all unique. B. Yes, because the sum of the probabilities is equal to 1 and the values are all unique. C. Yes, because the probabilities are all between 0 and 1, inclusive, and their sum is equal to D. No, because the sum of the probabilities is not less than 1. E. There is not enough information to tell.
