Re: [計量] 請教一題數學
※ 引述《stare (starE)》之銘言：
: 來自於印度JJ
: 4. There are rooms from 101 to 550 inclusive in which the starting
rooms are numbered from 1, 2, 3 and the waiting rooms are numbered
from 4,5,6. What is the probability that the rooms 4, 5, 6 will be
choosed randomly?
: 看不太懂題義>"<
房間從101到550
房號1 2 3開頭的為STARTING ROOM
4 5 6為waiting room
選到4 5 6開頭的機會有多少
韓網的解法 應該是這個翻義
