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...

Consider the following discrete probability distribution 15 22 P(X x) 0.14 0.38 0.27 0.21 xc 34 40 a. Is this a valid probability distribution? O Yes, because the probabilities add up to 1. O No, because the gaps between x values vary. b. What is the probability that the random variable X is less than 36? (Round your answer to 2 decimal places.) Probability c. What is the probability that the random variable X is between 12 and 30? (Round...
