[창의 퍼즐] [화학] 카와사키의 두 번째 실수

카와사키는 상점에서 '마법의 냄비' 10개를 주문하였다.
이 냄비는 재료를 넣으면 무조건 결합되도록 되는 냄비이다.
예를 들어 수소 분자 두 개와 산소 분자 한 개를 넣자마자 물이 된다.
이때, 어쩔 수 없이 분자는 탁구공 크기라 합시다. (저도 말 안되는 거 알아요)
카와사키는 로젤리나를 포함한 10명에게 요리를 하고 있다.
요리가 다 끝나자, 요리를 10등분하여 마법의 냄비를 옮기고
1/2 확률로 탈륨을, 1/3 확률로 산소를, 1/4 확률로 칼륨을, 1/5 확률로 탄소를 1/6 확률로 질수를 1/7 확률로 테크네튬을, 1/8 확률로 납은, 1/9 확률로 수소를, 1/10 확률로 황을 각각 마법의 냄비에 넣어 잘 섞고 10명에게 각자 나누어준다.
1. 요시가 납 중독으로 쓰러질 확률은?
2. 쿠파주니어가 청산가리 중독으로 쓰러질 확률은?
3. 로젤리나를 제외한 9명이 모두 어떠한 독 으로 쓰러질 확률은?
