Which of the following is the most widely used continuous probability distribution? The $—$ distribution.

• A. $Poisson$
• B. $Normal$
• C. $Geometric$
• D. $Binomial$

Answer: (B)

Verified step by step guidance

1. Understand that the question asks for the most widely used continuous probability distribution among the options provided.
2. Recall that the Poisson and Binomial distributions are discrete probability distributions, meaning they describe probabilities of countable outcomes.
3. Recognize that the Geometric distribution is also a discrete distribution, modeling the number of trials until the first success.
4. Identify that the Normal distribution is a continuous probability distribution, often used to model real-valued data that clusters around a mean.
5. Conclude that the Normal distribution is the most widely used continuous probability distribution among the given options.
