At a breakfast buffet, 63% of people choose coffee for their beverage while 23% choose juice. Also, 20% choose both coffee and juice. What percentage of people chose coffee only?

Answer 1

C=.63

J=.23

C&J=.20

C only= .63-.20=.43= 43% choose only Coffee

J only .23-.2 = .03 = 3% choose only Juice

1-66= 34% didn't choose either Coffee or Juice

43+3+20 = 66% chose Coffee, Juice or both
