In a class of 27 students, 16 liked video games and 20 liked cartoons. If 12 students like both video games and cartoons, how many students do not like either

Respuesta :

27 total students...
if 12 students like both, that means (16 - 12) = 4 students like only video games and (20 - 12) = 8 students like only cartoons.

27 - (4 + 8 + 12) = 27 - 24 = 3....3 students do not like either
