Quizplus · Accepted Answer

The probability of a student preferring meat topping given that the student is a junior is the number of juniors who prefer meat topping divided by the total number of juniors. From the table, we see that 11 juniors prefer meat topping and there are a total of 11 + 19 + 19 = 49 juniors. Therefore, the probability is 11/49 = 0.2245, which rounds to 0.229 to the nearest thousandth.
