Consider the following discrete probability distribution x 25 P(X = x) 0.18 22 9.36 34 0.27 40 8.19 a. Is this a valid probability distribution? 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 39? (Round your answer to 2 decimal places.) Probability c. What is the probability that the random variable X is between 9 and 30? (Round your answer to 2 decimal places.) Probability
