Question 861760: Hi Can you help with this problem. We need to chose the correct statement. I would also like to know how did you come to that answer.
Thank you in advance
A college survey claimed that 65% of students took English composition, 48% took calculus, 15% took both, and 7% took neither. Show that these figures cannot be correct.
A) The real percentage that took neither class is 15, not 7% as claimed by the survey
B) The real percentage that took both classes is 2, not 15% as claimed by the survey.
C) The real percentage that took neither class is 2, not 7% as claimed by the survey.
D) The real percentage that took both classes is 7, not 15% as claimed by the survey.

You can put this solution on YOUR website! C) The real percentage that took neither class is 2, not 7% as claimed by the survey.
.65+.48 = 1.03
1.03 - .15 = .98
1 - .98 = 2
