## Successive-Wins

To encourage Elmer’s promising tennis career, his father offers him a prize if he wins (at least) two tennis sets in a row in a three set series to be played with his father and the club champion alternately

father-champion-father
champion-father-champion
The champion is a better player than Elmer’s father

Which series should Elmer choose?

Elmer 如果在三场的系列赛中赢下连续的两场或三场，则可以得到奖励，系列赛的对手安排有两种

1. 爸爸-冠军-爸爸
2. 冠军-爸爸-冠军

# 思路参考

Elmer 与爸爸比赛获胜概率为 P1, 与冠军比赛获胜概率为 P2，由于冠军水平高于爸爸，所以 P1 > P2。
