A. From the table, we see that there were a total of 305 cars in the category of purchase price less than $20,000. Of these, 59 had total repair costs less than $10,000. Therefore, the probability is approximately 59/305, which is about 19.34%. So, the answer for Blank 1 is "about 19%."
B. To answer this question, we need to look at the row for total repair costs of less than $10,000. We see that there were a total of 296 cars in this category. Of these, 6 had a purchase price of more than $40,000. Therefore, the probability is approximately 6/296, which is about 2.03%. So, the answer for Blank 2 is "about 2%."
