No one is helping me :( Can someone please help me, I promise to mark brainliest. A survey was conducted among 400 students of age
groups 7-12 years and 13-18 years to find their
favorite music genre. The students had to select any
one genre out of jazz, rock, and pop. Out of the 200
students in the age group 7-12 years who participated
in the survey, 142 liked rock or pop music. The total
number of students of both age groups who liked jazz
was 72.
Using a two-way table, compute the total number of
students in the age group 13-18 years who liked rock
or pop music.

 186

Step-by-step explanation:

                     Jazz                      Rock or Pop  

7-12:          200 - 142 = 58                  142

13-18:        72 - 58 = 14                200 - 14 = 186

It is given that 142 out of 200 students in age group 7-12 like Rock or Pop.

Therefore, 200-142 = 58 in that age group like Jazz.

Total Jazz in both age groups is 72, so 72 - 58 (7-12: Jazz) = 14 students in age group 13-18 like Jazz.

There are 400 students total and 200 are in age group 7-12, which leaves 400-200 students in age group 13-18.  200 - 14 (13-18: Jazz) = 186 students in age group 13-18 like Rock or Pop.
