휠릭과 튈릭은 오늘 나올 점심이 중식인지 한식인지에 대해 싸우며 급식실에 들어갔다.
급식실에는 이렇게 쓰여 있었다.
<오늘의 식단>
중국식 가지덮밥(?)
쓰촨짜좡면(?)
탕슈만주(?)
1/16밖에 안되는 모두 같은 날인 것이다.
튈릭:봐! 오늘 중식 맞지.
휠릭:뭐 그렇다 쳐. 자랑 그만하고 빨리 줄이나 똑바로 서. 앞에 사람 없잖아!
그렇게 휠릭과 튈릭이 급식을 받은 뒤, 튈릭이 휠릭의 자리에 앉았다.
휠릭:왜 내자리에 앉아? 일어나!
튈릭:뭐? 일어? 일어보단 국어를 사랑해야지.
휠릭:그말이 아니잖아! 비켜라고!
튈릭:비를 켜라고? 그럼 우리 점심시간에 밖에 못나가잖아. 비오면 안돼.
휠릭:나와!빨리!
튈릭:너와 함께 뭘 하자고?
휠릭:우리반 학생 20명 중 10명이 너처럼 남의 자리에 앉는다면
나처럼 자기자리에 앉는 나머지 10명이 어떻게 되겠니?
문제:나머지 10명이 모두 자기 자리에 앉지 못할 확률은?
