[計量] 請教一題計量
Of the 7 members of the city council, 4 are Democrats and 3 are Republicans.
T is the total number of different 3-person committees that can be appointed
from the council membership such that each committee consists of 2 Democrats
and 1 Republican.
基本上題目根本看不懂= ="
different 3-person 就是指三個不同的人嗎????
然後從council挑選出來..........???
是比較T 跟 15
答案是T比較大
麻煩各位了
