Consider the following discrete probability distribution. x 15 22 34 40 P(X = x) 0.15 0.47 0.24 0.14 a. Is this a valid probability distribution? multiple choice Yes, because the probabilities add up to 1. 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.) c. What is the probability that the random variable X is between 12 and 27? (Round your answer to 2 decimal places.) d. What is the probability that the random variable X is greater than 18? (Round your answer to 2 decimal places.)
