#22
Determine whether or not the distribution is a discrete probability distribution and
select the reason why or why not.
21.
X
-3
9.
P(X = x)|0.22 0.69|0.09
Reason
A) Since the probabilities lie inclusively between 0 and 1 and the sum
of the probabilities is equal to 1.
Decide
B) Since at least one of the probability values is greater than 1 or less
A) Yes
than 0.
B) No
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 lie inclusively between 0 and 1.
