A questionnaire on popular singers has been filled by 200 girls from a high-school. The girls had to mark the singers from three most popular (Justin Timberlake, Justin Bieber and Axl Rose) which they like. Justin Timberlake got 78 votes, Justin Bieber got 75 votes and Axl Rose 101 votes. There were 28 girls which voted for all three singers. There were 22 girls which voted for two singers. One half of this amount are fans of the pair Bieber and Rose. The number of the girls which like only Justin Bieber is smaller by 7 comparing to the number of girls which like only Justin Timberlake.
