Consider the following discrete probability distribution. x 15 22 34 40 P(X = x) 0.14 0.40 0.26 0.20 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 40? (Round your answer to 2 decimal places.)

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.
In a certain year, 28.9% of all light vehicles were light trucks, 28.9% were SUVS, and 42.2% were cars. The probability that a severe side-impact crash would prove deadly to a driver depended on the type of vehicle he or she was driving at the time, as shown in the table. What is the probability that the victim of a deadly side-impact accident was driving an SUV? (Round your answer to four decimal places.) Light Truck .210 SUV .371 Car 1.000 Need Help? Watch It
