Explanation:

To determine the correct graph of \( p(x) \), we analyze the shape and distribution. The graph in option C shows a distribution that likely corresponds to the given context (e.g., a probability or frequency distribution with a pattern that matches the expected \( p(x) \) behavior, such as a more continuous or increasing-then-decreasing pattern, unlike the sparse or uneven distributions in A and B).

Answer:

C. The graph labeled C (with \( p(x) \) on the y - axis, showing a small bar at 10, then increasing bars at 20, 30, and a slightly smaller bar at 40)
