휠릭이 점심을 다 먹고 가려고 하자 튈릭이
"가지마...!"
라고 했다.그러자 휠릭이 아직 화나서"니가 뭔데 나보고 가지말라고 하냐?"라고 하자,
튈릭:내가 언제?"난 가지마···ㅅ있었냐?"라고 물어보려는 거였는데.
휠릭:나? 가지 맛없었어.
튈릭:난 오늘 가지덮밥 맛있었는데.
휠릭:그럼 내가지는 맛없고 니껀 맛있었나보지. 난 그냥 간다.
튈릭:잠시만, 내 얘기 듣고 가!
너껀 맛없었고, 내껀 맛있으니까 맛없을 확률과 맛있을 확률이 다 1/2이잖아,
그러면 100명한테 물어보면 50명정도가 맛있다고 하겠네.
문제:튈릭의 말은 옳은가? 아니라면 어디가 잘못되었는가?
