Use a venn diagram

in a school of 343 students. 115 students are in music. 197 students are on sport teams and 69 students participate in both activities. how many students are involved in either music or sport? how many students are not involved in either sport or music.

243 students are involved in either sports or music whereas 100 are not

involved in either of it.

Step-by-step explanation:

No. of students who are in music = 115

No. of students who are in sports = 197

No. of students who are in both activities = 69

So, no. of students who are involved either in sports or music,

= (115 + 197 - 69)

=243

So, no. of students who are not involved in either sports or music,

= (343 - 243)

=100

step-by-step explanation:

the first one, all those points on the line just make a strait line.
