Question

Identify the requirements for a discrete probability distribution. Choose the correct answer below. A. There must be a fixed number of independent trials. There must be two mutually exclusive outcomes for each trial with a constant probability of success. B. The sum of the probabilities must equal one. Each probability must be between zero and one inclusive. C. Each probability must be between zero and one inclusive. D. The sum of the probabilities must equal one.

Answer 1

B. The sum of the probabilities must equal one. Each probability must be between zero and one inclusive

Explanation:

The discrete probability distribution is a distribution in which the random variable would be considered as countable i.e. non-negative digits also it would be presented in table form

So according to the given situation, the option b is correct as their sum would be equivalent to zero also each probability should be lies between zero and one inclusive
