To find the percentage chance that if a farmer prefers to grow carrots they have Rocky soil, we need to calculate the relative frequency of farmers who prefer to grow carrots and have Rocky soil.
Relative frequency = (Number of farmers who prefer carrots and have rocky soil) / (Total number of farmers who prefer carrots)
Relative frequency = 250 / 220 = 1.1364
Next, we convert this relative frequency to a percentage by multiplying by 100.
Percentage chance = 1.1364 * 100 = 113.6%
Rounded to the nearest tenth, the percentage chance is 113.6%, which is closest to 100.0%.
Therefore, the answer is B. 100.0%.
Examine the data from a survey of farmers about their different soil types and the crops they prefer to grow. Using relative frequencies, what is the percentage chance that if a farmer prefers to grow carrots they have Rocky soil? Round your answer to the nearest tenth.
