Consider the following discrete probability distribution. x 15 22 34 40 P(X = x) 0.13 0.49 0.24 0.14 a. Is this a valid probability distribution? 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 38? (Round your answer to 2 decimal places.) c. What is the probability that the random variable X is between 10 and 28? (Round your answer...
