Consider the following discrete probability distribution.
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 36 ? (Round your answer to 2 decimal places.)
