Re: [請教] 請問幾題模考的題目(已修改)
※ 引述《INR202 ()》之銘言：
: 題目是要問:A和B何者較大?
: 問題1:
: seven one-dollar bills are to be distributed among Lucia, Gomes
: and Domingo so that each person receives at least $1.
: A:The number of was to distribute the
: bills so that at least one person receives at least $3
: B:The total number of ways to distribute the bills.
: 為什麼答案是一樣大??
既然每個人至少要拿一張鈔票，就先給下去。然後考慮剩下四張給三個人分的狀
況。如同Column B隨便亂分的話，根據鴿籠原理，至少有一個人要再拿兩張，剛
好又符合Column A，所以相同。
: 問題2:
: If the assets of a certain mutual fund drored by $3.04
: billion to $72.04 billion, what was the approximate percent
: decrease in the fund`s assets?
: ans: 4%
總資產下跌3.04B跌到72.04B，則原來資產就是75.08B，因此下跌百分比就是，
3.04/75.08，差不多是4%。
: 問題3:
: Which of the following is both the mean and median of 7
: consecutive integers the least of which is X?
這題沒給那七個連續整數哩～
: 謝謝各位~感激不盡!!
