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


Decide: Yes or no?

Reasons:
a) Since the probabilities lie inclusively between 0 and 1 and the sum of the probabilities is equal to 1

b) Since at least one of the probability values is greater than 1 or less than 0

c) Since the sum of the probabilities is not equal to 1

d) Since the sum of the probabilities is equal to 1

e) Since the probabilities is lies inclusively between 0 and 1
