[문장제 문제&개념응용] [연산]확률의 세계 12: 귀국(시즌 1 완결)

확률 퀴즈대회는 신기하게도 확률이 엄청 높은 팀도 있었지만 뽑기를 했더니 우승에 당첨된 사람이 없었다
결국 동동이는 기분이 안좋아 다시 리만가설의 몸으로 돌아왔다
그래서 수락이와 친구들은 화해하고 이제 확률의 세계를 떠나기로 했다
그런데 확률의 세계는 다시 집으로 돌아갈 확률을 구하라고 했다
수락이는 당연히 자신들이 집으로 돌아갈 것이니까 100% 라고 했는데 틀렸다
확률의 세계의 대통령은 문제를 냈고 그 문제의 답의 33%의 6배의 99%의 23%가 수락과 친구들이 집으로 갈 확률이라고 했다
마지막 문제는
당신들이 이번 확률의 세계에서 확률 퀴즈대회에 나갔다
확률 퀴즈대회에서 우승자가 없었지만 우승자를 한명 정한다
그 우승자가 당신들이 될 확률은 지금까지의 확률의 세계 문제들의 답의 합의 22%이다(이게 무슨 말이나면 확률의 세계 1~11까지의 답의 합의 22%라는 말이다)
그렇다면 당신들이 우승할 확률은 얼마인가

와 시리즈가 이렇게 많은데 그런걸 다 기억하세요

근데 사실 전 1~11부터의 답 중 3,4,5번의 풀이를 잃어버렸다는... (뭐 그래도 다시 풀면 되지...)
