Hi Brandon,

Total no of students = n( total students)= n(T)=300

No of students in Chorus= n( students in Chorus)=n(C)=110

No of students in band= n( band students) =n(B)=150

No of students in both chorus & the band= n(C & B both)=50

no of students in chorus or in Band= = n(C or B)=n(C)+n(B)-n(C&B)= 110+150-50=210

No of students neither in Chorus nor in Band= n(T)-n(C orB)=300-210=90
