问题描述 "

1、蓝色、红色、白色三种颜色的彩球,每种彩球8颗;

" "

2、每次从黑色不透明袋子里随机抓出12颗;

" "

3、每次抓出的彩球按照颜色分类,然后统计出每种颜色的颗数;

" "

4、对照颜色颗数的组合列出3位数字;

" "例如:蓝色、红色、白色彩球各8颗;

随机抽出12颗彩球,这12颗彩球内包含3颗篮球、4颗红球、5颗白球;

列出的组合数字即为345;

" "上面是题目,需要下面的答案:" "

1、这24颗彩球每次抓取12颗(抓完一次以后又将彩球全部放回袋子内),可能出现的数字组合有哪些?需要用EXCEL一一列出;

" "

2、如果只抓取一次彩球,那么各种组合在这一次内出现的概率有多少?用%比列出;

" "

3、如果抓取10次彩球,那么各种组合在这10次内出现的概率有多少?用%比列出;

" "

4、如果抓取100次彩球,那么各种组合在这100次内出现的概率有多少?用%比列出;

" "

5、如果是两种颜色、每种颜色4颗,随机抓出4颗的结果?" "

6、如果是两种颜色、每种颜色8颗,随机抓出6颗的结果?" "

7、如果是三种颜色、每种颜色4颗,随机抓出4颗的结果?" "

8、如果是三种颜色、每种颜色8颗,随机抓出6颗的结果?" "

9、每种结果需要附上计算方法以及详细计算公式及公式符号说明等内容!" 1,840,831,822,813,804 750,741,732,723,714,705 660,651,642,633,624,615,606 570,561,552,543,534,525,516,507 480,471,462,453,444,435,426,417,408 381,372,363,354,345,336,327,318 2,"1/43=2.
