Suppose you want to gamble on the NBA final (best of 7 series, the first team to win 4 games wins the sereis and no more games are played) of team A and B, and you support team A. You can bet any amount, say X, before each game, if team A wins, you get paid by 2X, otherwise, you lose the X. Your goal is that you win exactly $100 if team A wins the series, or lose exactly $100 if team B wins the final. Is this possible? If yes, what's you betting strategy?
可能。 构造如下数组: 0 31.25 62.5 87.5 100 每个数表示每次bet完后所赢钱数,初始位置为左上角,赢了则向右移动一步,输了向下移动一步,bet的 钱数=|目的钱数-初始钱数|。 如,第一次bet钱数是31.25。 |
