A survey was take of 180 people. Each was asked to choose their one favorite type of music. 2/3 of respondent chose classical and 1/3 chose jazz. how many of people surveyed chose neither classical music or jazz?
I don't understand his explanation of "60 people prefer jazz/pop (2/3), 40 prefer pop"
Isn't 2/3 of the respondent 120 people for classical and the 1/3 60 for jazz?
