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 ?
Thanks, I already did this one but I do think that was the answer
To find the number of students who studied only in the cafeteria, we need to subtract the number of students who studied in both the cafeteria and the student lounge from the total number of students who studied in the cafeteria.
Total number of students who studied in the cafeteria = 78
Number of students who studied in both the cafeteria and the student lounge = 22
Number of students who studied only in the cafeteria = Total number of students who studied in the cafeteria - Number of students who studied in both the cafeteria and the student lounge
Number of students who studied only in the cafeteria = 78 - 22 = 56
Therefore, 56 students studied only in the cafeteria.
