1. 난이도: 매우 쉬움.
관종이는 만두를 먹으면서 폴리매스를 하고 있다.
만두의 종류는 고기, 김치, 망고, 블루베리, 그리고 팥 만두가 4개씩 있다. (사실은 고기와 김치만 있습니다!)
관종이는 오로지 고기만 좋아하기 때문에 다른 만두들을 혐오하는 정도로 싫어한다.
관종이는 이때, 만두 2개를 무심코 집었을 떄, 왼쪽에는 고기, 오른쪽에는 망고일 확률은?
2. 난이도: 어려움.
갑자기 아빠가 들어와 관종이가 더 혐오하는 딸기, 초콜릿 그리고 바나나 만두를 2개씩 놓고 갔다.
관종이가 다시 만두를 4개씩 집을 때,
망고/블루베리/김치/바나나의 조합이 나올 확률은?
