Question

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

x −4 3 6
P(X=x) 0.35 0.62 0.36

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

 
(yes or no)
 
REASON

(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 tie inclusively between 0 and 1.
