To find the percentage chance that a farmer who prefers to grow carrots has rocky soil, we will use the data provided in the table.

  1. Identify the total number of farmers who prefer carrots.

    • From the table, the total number of farmers who prefer carrots is 220.
  2. Identify the number of farmers who prefer carrots and have rocky soil.

    • From the table, 100 farmers with rocky soil prefer carrots.
  3. Calculate the relative frequency (percentage) using the formula:

\[ \text{Percentage} = \left( \frac{\text{Number of farmers with rocky soil preferring carrots}}{\text{Total number of farmers preferring carrots}} \right) \times 100 \]

Substituting the numbers:

\[ \text{Percentage} = \left( \frac{100}{220} \right) \times 100 = 45.4545\ldots \approx 45.5% \]

After rounding to the nearest tenth, the answer is:

45.5%

The correct response is 45.5%.
