◆FAMILY TEAMS
Four families, each with four members (mother, father, daughter and son)
apply to attend a competition. Three teams of three people will be selected.
Each team will have exactly one mother, one father and one child (daughter
or son) and none of the members will be from the same family.
How many different ways the teams can be formed? (Two formations are
considered the same if team memberships are the same but team orders are
different.)
有四個家庭,每個家庭有四個成員(父、母、子、女),報隊要參賽。共組三個隊伍,
一隊三人。每個隊伍都要有一位媽媽、一位爸爸、跟一個小孩(男孩或女孩),且這三
人都要來自不同家庭。
問有幾種組成隊伍的方法?(隊伍成員相同僅隊伍順序不同視為相同組合。)
原譯註:竟然少一個條件,就是每個家庭至少都要有一人參賽,不然三個家庭也可以組隊。
譯註:乍看之下還以為會有個條件是每家至少要出一人,看來沒有,三個家庭也能組隊
