is it C?

jimthompson5910 (jim_thompson5910):

how did you get C?

OpenStudy (calculusxy):

300 + 700 = 1000 1000 - 800 = 200

It's not really 100% clear. The 800 people like either genre or both? Or they are just the ones surveyed, and some people don't like either genre?

OpenStudy (calculusxy):

that's all there is to the question

jimthompson5910 (jim_thompson5910):

If you go with the assumption that 800 people like either genre or both, then there are 200 people who like both. So if that assumption is true, then your answer is correct
