一个六面色子扔10次,正好只有一次六的概率是多少,如果已经知道至少已经扔了一个六?
原题是
A single die is rolled 10 times.
What is the probability that a six is rolled exactly once,if it is known that at least one six is rolle?

一个六面色子扔10次,正好只有一次六的概率是多少,如果已经知道至少已经扔了一个六?原题是A single die is rolled 10 times.What is the probability that a six is rolled exactly once,if it is known that at least one six i
如果已经扔了一次6
那么也就是其余9次都不是六,p=(5/6)^9
如果已经扔了超过1次6
那么很明显概率是0了

一个六面色子扔10次,正好只有一次六的概率是多少,如果已经知道至少已经扔了一个六?原题是A single die is rolled 10 times.What is the probability that a six is rolled exactly once,if it is known that at least one six i 三个色子一起抛,出现一个六的几率是多少? 连续掷五次色子都没有六点 ,那幺第六次掷色子是六点的概率是多少? 某人掷一个均匀的色子4次至少得到一个6点和同时掷两个色子24次至少得一双六的概率各为多少?哪一个机会更大? 随机地掷一个色子,连掷6次,则恰有1次出现“六点”的概率是不是 C6.1*(1/6)^1*(5/6)^5 1个色子丢10次,只有一次是6的几率是多少RT,请写出详细过程..谢谢 一个色子连投两次,点数和为六的概率是几? 六个色子,一块掷,至少有一个六点的概率是多少?晕啊 一个六面骰子,连投30次,结果总值在150以上的概率有多少?怎么计算?RT 将两颗色子各掷一次,设事件B=两个点数不相同,A=出现一个六点,则概率P(AIB)等于? 一个概率掷色子的问题.两个色子同时扔,掷180次,求:1)至少有25次点数之和等于7的概率2)点数之和等于7的次数在33-41的概率3)正好30次点数之和等于7的概率 如果你连掷一个色子6次,6种点数每种分别掷到一次的概率是多少. 摇色子赌单双摇一千次色子,连续出单或双和一次单一次双的概率问题 -64的六次方根 256的六次方根 魔方六面的公式 六面魔方的口诀 把一个正方体的六面分别标上字母
