A. 60.0%
B. 75.0%

1 answer

To find the percentage chance that farmers with rocky soil prefer growing peppers, we need to use the relative frequency of the intersection between the "Rocky Soil" column and the "Peppers" row, divided by the total number of responses:

Relative frequency = 150 / 420 = 0.3571

To convert this to a percentage, we multiply by 100:

Percentage chance = 0.3571 * 100 = 35.71%

Therefore, the answer is not one of the options provided. The closest answer would be C. 66.7%, but this is incorrect.
