In the group of hundred students68 likes football 60 likes volleyball how many likes only football

i think 40

if 68 =likes foot ball

&60=likes volley ball

here there are available the students that likes both because 68+60=128 but the students are 100 so the students that likes both are 128-100=28

threfore the students that like only football are 40

cause the 68 likes football & the28 likes only football

so to know how many students likek foot ball evaluate like this (68-28=40)

i hope helps you
