Ответ:
324 : students who said they spend more than 1 hour every day "video games"
368 : students who said they spend more than 1 hour every day "studying"
87 : students who said they spend more than 1 hour in playing & studying
and 221 students who are neither playing nor studying:
324 + 368 +87 + 221 = 1,000
87 only were playing and studying , or 87/1000 = 0.087
