11. Which of the following is a discrete probability distribution?

I. Normal distribution
II. Geometric distribution
III. Poisson distribution
IV. Chi-Squared distribution

a. Only I
b. II and III
c. I and IV
d. I, II, and III
e. Only II



Answer :

Final answer:

Discrete probability distributions involve specific, countable outcomes like the geometric and Poisson distributions.


Explanation:

Discrete probability distributions are distributions where the random variable can only take on specific values, typically integers. The geometric distribution and Poisson distribution are examples of discrete probability distributions because they deal with countable outcomes, such as the number of trials until a success occurs or the number of events in a fixed interval, respectively.
