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

x 3 6 7

P(X=x) .55 .38 .07

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

Decide Yes or No

Reason

• Since the probabilities lie inclusively b/w 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.
