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.
To find the percentage chance that if a farmer prefers to grow carrots they have rocky soil, we need to divide the number of farmers who prefer to grow carrots and have rocky soil by the total number of farmers who prefer to grow carrots.
The number of farmers who prefer to grow carrots and have rocky soil is 100.
The total number of farmers who prefer to grow carrots is 220.
So, the percentage chance is (100/220) * 100 = 45.5% (rounded to the nearest tenth).
Therefore, the percentage chance is 45.5%.
