In a survey of 100 students it is shown that 40 students have season football tickets, 30 students have basketball season tickets, and 20 students have both football and basketball season tickets. How many students have NEITHER basketball NOR football season tickets?

Respuesta :

40+30+20=90 (number of people with tickets; out of 100)
100-90=10
10 people had neither basketball nor football season tickets
10 people didn't have either tickets
