A college survey was taken to determine where students study. Of 132 students surveyed, 78 studied in the cafeteria, 64 studied in the student lounge, 22 studied in both the cafeteria and the student lounge.
Of those interviewed how many studied only in the cafeteria ?

surely that would be 78-22 = 56, right?
Thanks, I already did this one but I do think that was the answer
