Suppose that there are 26 students in a class. Out of those students, 12 play in a band and 8 sing in a choir. If 4 of these students joined both the choir and the band, how many students didn’t participate in any?​

Sagot :

Answer:

26(all students) - 12(plays band) = 18 - 8(sings choir) = 10 - 4(both plays band and sing choir) = 6 students didn't participate
