The graph shown in the image depicts a uniform distribution, as indicated by its rectangular shape where the probability density is constant over a specific interval (from $x=3$ to $x=7$) and zero elsewhere.

Correct Answer:

b. uniform distribution

Would you like further clarification or more details on why this is a uniform distribution?

Here are some follow-up questions to deepen your understanding:

1. What are the key characteristics of a uniform distribution?
2. How is a uniform distribution mathematically defined?
3. What are some practical applications of uniform distributions in real life?
4. How does the uniform distribution differ from the exponential and binomial distributions?
5. What is the total probability under the curve for any valid probability distribution?

Tip: In any probability distribution, the area under the curve (or the sum of probabilities) equals 1.
