有鑑於板上最近題目較少,因此來貢獻一題....這題應該也是不少人看過..
你參加一場射擊生存遊戲,遊戲規則是這樣:
1.每個人都有一把玩具槍,大家輪流射擊彼此,一次只能射一發(子彈無限)
你要對準誰都可以(提示:包括可以對空鳴槍喔>.^)
2.被射中的玩家頭上的燈會亮起,代表死亡,立即退出遊戲。
3.輪流射擊,直到剩下一名玩家生存
現在你(代號為A)和B、C共三個人輪流射擊,你的射擊命中率30%、B
的射擊命中率50%,C是神槍手,射擊命中率100%!!
為了公平起見,你們射擊順序是
你->B->C->然後又輪回你(掛掉的話當然就跳過)......
這邊每個人彼此之間都很聰明,也都很想贏得遊戲。
現在你要開始射擊了.....你稍微想一下,如果射擊B、不小心讓B出局了,接著
輪C,下一回合你百分之百出局。因此似乎先射擊C比較好.......
但等等,其實你有更好的策略,是什麼呢?
大家如果都用最佳策略,你在這場遊戲勝出率是多少呢?
---------------
延伸:如果這一題你秒殺的話,試著去想,假設又加進來一個人K,命中率是70%
採取A->B->K->C....順序
大家都用最佳策略,你勝出機率有多少?
