To determine the empirical probability of a customer ordering a milkshake, we need to look at the total number of milkshake orders and divide that by the total number of orders. From the given table, we can see that there were 27 + 43 + 10 + 5 = 85 total milkshake orders. And the total number of orders is the sum of all the entries in the table, which is 25 + 10 + 27 + 33 + 20 + 15 + 43 + 17 + 18 + 12 + 10 + 5 + 12 + 8 + 5 + 10 = 260.

So the empirical probability of a customer ordering a milkshake is

To determine the empirical probability of a customer ordering a milkshake, we need to add up the number of milkshakes ordered and divide by the total number of orders. According to the table, the total number of milkshakes ordered is 27 + 43 + 10 + 5 = 85. The total number of orders is the sum of all the entries in the table, which is 25 + 10 + 27 + 33 + 20 + 15 + 43 + 17 + 18 + 12 + 10 + 5 + 12 + 8 + 5 + 10 = 260. Therefore, the empirical probability of a customer ordering a milkshake is 85/260 = 0.327 or approximately 33%. Therefore, the answer is 0.330.
