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

Decide Yes NoReason Since the probabilities lie inclusively between 00 and 11 and the sum of the probabilities is equal to 11. Since at least one of the probability values is greater than 11 or less than 00. Since the sum of the probabilities is not equal to 11. Since the sum of the probabilities is equal to 11. Since the probabilities lie inclusively between 00 and 11.
