G Turn in Test HSC 544_Exam 2 Question 16 of 20 Step 1 of 1 00:38:00 Determine whether or not the distribution is a discrete probability distribution and select the reason why or why not. P(X-X) | 0.53 | 0.34 | 0.18 Answer 2 Points Keypad First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision. Decide Prev O Yes No Next Reason Since the probabilities lie inclusively between 0 and 1 and the sum of the probabilities is equal to 1 Since at least one of the probability values is greater than 1 or less than 0. Since the sum of the probabilities is not equal to 1 Since the sum of the probabilities is equal to 1 Since the probabilities lie inclusively between 0 and1 © 2018 Hawkes Learning

Explanation / Answer

Here the decision should be No

As we see that the sum of probabilities for discrete points -1,3,8

is 0.53+0.34+0.18 = 1.05

which is greater than 1.

Therefore Option 3 is correct, in fact it is not a distribution function.
