수학동아 - 폴리매스
함께 풀고 싶은 문제
나도 수학쌤 문장제 문제를 변형해 문제를 내는 곳입니다.
[문장제 문제&개념응용] [확률] 확률문제 패러독스

수락은 어떤 문제를 폴리매스에서 내려고 한다
수락이 확률문제를 낼 확률은 80%이고 창의문제를 낼 확률은 10%, 세상을 바꿀 문제를 낼 확률은 2%이고 확률을 제외한 다른 개념응용 문제를 낼 확률은 8%이다
수락이 이러한 조건의 문제를 연속을 낼때는 1번 연속할때마다 다음에도 똑같은 문제를 연속해서 낼 확률이 원래에 비례해 5% 줄어든다
수락은 11시에 잘 확률이 50%, 12시에 잘 확률이 30%, 1시에 잘 확률이 20%이다
당신이 다음날 일어났을때 수락의 확률문제가 10개 연속 도배되었을 확률은 얼마인가
단, 다른사람이 수락이 문제를 내는동안 문제를 내지 않았다고 가정하자
