[計量] 一題關於鴿籠原理的計量
在寫補習班講義時看到一題覺得答案頗怪,想問版上其他版友們的意見@@"
If there are 33 balls arranged in the 7 different boxes,
which of the following is true?
I. At least one of the boxes has more then one ball.
II. At least one of the boxes has 4 balls.
III. At least one of the boxes is empty.
答案是I&II
我想知道為什麼會有II.....
怎麼樣都想不通 希望版友幫忙解答囉;D
