150.0%
60.0%
75.0%
66.7%
To find the percentage chance that farmers with rocky soil prefer growing peppers, we first need to calculate the relative frequency of farmers with rocky soil who prefer growing peppers:
Number of farmers with rocky soil who prefer growing peppers = 150
Total number of farmers with rocky soil = 250
Relative frequency = Number of farmers with rocky soil who prefer growing peppers / Total number of farmers with rocky soil
Relative frequency = 150 / 250
Relative frequency = 0.6
To convert the relative frequency to a percentage, we multiply by 100:
Percentage chance = 0.6 * 100
Percentage chance = 60%
Therefore, the percentage chance that farmers with rocky soil prefer growing peppers is 60%, rounded to the nearest tenth.
So, the correct answer is:
