그렇게 3명의 파죽지세로 경쟁자들을 해치워나갔고... 단숨에 8강전까지 올라왔다.
백작: 브라보~!! 지금까지의 경쟁자들을 물리치고 올라온 참가자 8명들에게 환호의 박수를! 그러면, 준결승전을 향한 치열한 싸움을 한 번 볼까요?
김민호: 어떡하지... 이제 1vs1 싸움이 4번밖에 없으니까... 우리끼리 만날 확률이 높을 것 같은데... 이러다가 어쩌지...
한수진: 대충 짐작하지만 말고 빨리 계산해봐요!!!
(문제) 8강전에는 8명의 선수들이 싸우게 된다. 8명의 선수들 중 김민호, 한수진, 박진우 3명이 같은 팀이고, 8명 중 랜덤으로 2명씩 겨루어 결투를 하는 토너먼트식 대회일때, 같은 팀끼리 만날 확률은?
