Determine whether or not the distribution is a discrete probability distribution and select the reason why or why not.

x	3	1	5
P(X=x)P(X=x)	5/8	1/8	1/4

First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision.

Decide

Yes No

Reason

Since the probabilities lie inclusively between 0 and 1 and the sum of the probabilities is equal to 1.

Since at least one of the probability values is greater than 1 or less than 0. Since the sum of the probabilities is not equal to 1.

Since the sum of the probabilities is equal to 1.

Since the probabilities lie inclusively between 0 and 1.
