這是老師自己想的題目我目前還沒想到怎麼去解他

有三對女雙胞胎跟三對男雙胞胎結婚

每兩姊妹都是跟兩兄弟結婚

有天他們十二個人出去打網球他們要打mix double

所以只能找異性的當隊友然後又避免默契太好

不能挑自己的老婆或是老婆的姊妹當隊友

請問這樣總共有幾種組合

6*((2*2*2)+(2*2*2))=96?

[(2*2*2)+(2*2*2)]+(2*2)*(1*2)*(2*1)]=32

2*2*2+2*2*2+8*4*4=144

算式也跟你一樣我把所有可能都列出來了

我的是 (4x1)(2)(2) + (4x2)(2^3) = 80

大家可以解釋一下自己的想法這樣我數學才會進步XD

你的方法不錯了,之前的種數算法可以不用列舉

前兩格配同一對雙胞胎,之後的就都固定了,配bb或cc共2種

前兩格如果放不一樣,bc,那中間兩格就只能ac,後面兩格ab

兩格一組的可以交換位置,所以是2^3=8種

By Jacky

全部就是2+8=10種,然後雙胞胎自己可交換故10*8=80種
