보물을 찾은 뫼비우스와 탄지로!그.러.나
문제:이 보물상자는 비밀번호가 없어서 활이나 창,도끼로 보물상자를 깨 부숴야 한다.보물상자는 1데미지를 입으면 박살난다.
도끼로 찍어서 보물상자에 1/3데미지를 입힐 확률:2/3
창으로 찔러서 보물상자에 1/3데미지를 입힐 확률:1/2
활로 보물상자를 쏘아서(?)보물상자에 1/3데미지를 입힐 확률:1/3
도끼의 불량률:1/12(불량이면 도끼로 데미지를 입힐 수 없음)
창의 불량률:1/13
활의 불량률:1/14
도끼는 4번 찍을 수 있다.
창은 5번 찌를 수 있다.
활은 6번 쏠 수 있다.
보물상자를 깰 확률을 높이려면 어떤 무기를 사용해야 할까(?)
단 무기는 1개밖에 선택할 수 없다.
풀이 필수입니다.
