Answer 1

Answer:

since i don't dislike teacher a and teacher b so i am the 50% . now i don't care how many disliked both the teachers . lmao

Answer 2

total number of students - 80

number of students who dislike teacher A - 20%

number of students who dislike teacher B - 30%

number of students who dislike no teacher - 50%

--------------------------------------------------------------------------------------------------------------number of students who dislike teacher A - 20%

= 80/20 = 16 students

number of students who dislike teacher B - 30%

= 80/30 = 24

--------------------------------------------------------------------------------------------------------------

number of students who dislike teacher A & B = 16 + 24 = 40
