Question Analysis
This question involves a two-way frequency table with variables "color" (black/silver) and "car type" (sedan/SUV).
The main focus is on determining the marginal frequency for the "Silver" row.

Key Concept Explanation
Marginal Frequency (Row): The total count of items in a row, calculated by summing the joint frequencies within that row. It represents the total for one category of the row variable (e.g., all silver cars, whether sedans or SUVs).

Step-by-Step Solution
Locate the row labeled "Silver".
The marginal frequency for this row is the "Row Total" at the end of the row, which is 40.
