Number of students that like neither tea or coffee is 11
Total number of students = 50 (Given)
Number of students that like tea = 30 (Given)
Number of students that like coffee = 25 (Given)
Number of students that like both tea and coffee = 16 (Given)
Therefore,
Number of students who like neither tea or coffee =
Total number of students - (Number of students who like tea + Number of students who like coffee - Number of students who like both tea and coffee)
= 50- (30 + 25 - 16)
= 50 - ( 55 - 16)
= 50 - 39
= 11
Hence, the number of students that like neither tea or coffee is 11
