Please help ASAP!

George believes the Art Club students at his school have an unfair advantage in being assigned to the art class they request. He asked 500 students at his school the following questions: "Are you in the Art Club?" and "Did you get the art class you requested?" The results are shown in the table below:



Art Club Not in Art Club Total

Received art class requested 100 265 365

Did not get art class requested 65 70 135

Total 165 335 500



Help George determine if all students at his school have an equal opportunity to get into the art class they requested. Show your work, and explain your process for determining the fairness of the class assignment process.

165 total students in art club. 100 of those got the requested class.

100/165 = 0.6061


335 total students not in art club. 265 got the requested class.

265/335 = 0.7910


the probability was higher for kids not in art club, so all students had an equal opportunity.
