英文数学难题(English Maths)
我之前考了一题这样的数学题:
Two fair dice were tossed,the sum of two number obatained were even number.Find the probabilities at least a "4" is obtained.
搞不清是要求“这两个数至少有一个是4的机会”还是“两个数的和最小是4的机会”

是“至少有一个是4”,因为是a "4" - 注意4前面那个“a”,表示其中一个数.
如果是和,会说the sum of the two numbers is 4之类.
两个公平的骰子投掷了,两个数的概率也number.Find obatained至少一个“4”。
两个公平的骰子投掷了,两个数的概率也number.Find obatained至少一个“4”。
两个数的和最小是4的机会
同时,和为偶数。
这是一个条件概率
可以为4,6,8,10,12
为4时。
1,3
2,2
为6
1,5
2,4
3,3
为8
2,6
3,5
4,4
为10,
4,6
5,5
为12,
6,6
。。。。。
两个数的和最小是4的机会
同时,和为偶数。
这是一个条件概率
可以为4,6,8,10,12
为4时 1,3 2,2
为6 1,5 2,4 3,3
为8 2,6 3,5 4,4
为10 4,6 5,5
为12 6,6
两个公平的骰子投掷了,两个数的概率也number.Find obatained至少一个“4”。
