Andrew believes the honor roll students at his school have an unfair advantage in being assigned to the math class they request. He asked 500 students at his school the following questions: "Are you on the honor roll?" and "Did you get the math class you requested?" The results are shown in the table below:
Honor roll Not on honor roll Total
Received math class requested 215 125 340
Did not get math class requested 80 80 160
Total 295 205 500

Calculate P(received math class requested|Honor roll) and evaluate whether the two events appear independent.
