Is the distribution a discrete probability distribution?
A. Yes, because the sum of the probabilities is equal to 1.
B. Yes, because each probability is between 0 and 1 , inclusive.
C. No, because the-sum of the probabilities is not equal to 1.
D. Yes, because the sum of the probabilities is equal to 1 and each probability is between 0 and 1 , inclusive

Answer

Final Answer: \(\boxed{\text{(D) Yes, because the sum of the probabilities is equal to 1 and each probability is between 0 and 1 , inclusive}}\)

Steps

Step 1 :Given the distribution table, we need to determine whether it is a discrete probability distribution. The conditions for a distribution to be a discrete probability distribution are: each probability is between 0 and 1, inclusive, and the sum of all probabilities is equal to 1.

Step 2 :First, we check if each probability is between 0 and 1, inclusive. Looking at the table, we can see that all probabilities are indeed between 0 and 1.

Step 3 :Next, we need to check if the sum of all probabilities is equal to 1. We do this by adding all the probabilities: \(0.26 + 0.12 + 0.21 + 0.25 + 0.16\).

Step 4 :The sum of the probabilities is 1. Therefore, both conditions for a discrete probability distribution are met.

Step 5 :Final Answer: \(\boxed{\text{(D) Yes, because the sum of the probabilities is equal to 1 and each probability is between 0 and 1 , inclusive}}\)
