Determine whether or not the distribution is a discrete probability distribution and select the reason why or why not. -2 4 8 P(X = x) Answer First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision. Decide O Yes O No Reason O Since the probabilities lie inclusively between 0 and 1 and the sum of the probabilities is equal to 1. O Since at least one of the probability values is greater than 1 or less than 0. O Since the sum of the probabilities is not equal to 1. O Since the sum of the probabilities is equal to 1. O Since the probabilities lie inclusively between 0 and 1
