UVA10759 - Dice Throwing（dp+gcd）
题目链接
题目大意：n个色子，求n个色子之和不小于x的概率。
解题思路：因为可以将题目转化成求n个色子和小于x的数目，最后再6^n减去就这个数目就是大于等于x的数目了。因为n最大就24，这样还是可以用long long来存放，最后输出要求的是分数形式，将分子分母用gcd约分一下输出即可。

n个面的骰子 求每个面至少扔到一次的期望值
设dp[i]为已经扔了i个不同面的期望值 dp[n] = 0 求dp[0]
因为dp[i]为还需要扔i个不同的面 每次可能扔中已经扔过的面或者没有扔到过的面2中情况
所以dp[i] = (i/n)*dp[i] + (n-i)/n*dp[i+1] +1 等号2边都有dp[i]
移项得dp[i] = dp[i+1]+n/(n-i)
