Consider the following discrete probability distribution.


x	15	22	34	40
P(X=x)	0.14	0.51	0.21	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 variableXis less than 40?(Round your answer to 2 decimal places.) c.What is the probability that the random variableXis between 14 and 26?(Round your answer to 2 decimal places.) d.What is the probability that the random variableXis greater than 18?(Round your answer to 2 decimal places.)
