再来一个随机漫游问题

Input x value(0 to EXIT):4 m(total) = 9, n(odd) = 8 Input x value(0 to EXIT):4 m(total) = 16, n(odd) = 11 Input x value(0 to EXIT):4 m(total) = 16, n(odd) = 12 Input x value(0 to EXIT):0

弄反了 呵呵

如果每次以均等概率向前走x的距离或者向后走1的距离(x>1),那么最后能够返回起始位置(或之前)的概率是多少? 你的叙述有问题啊 我怎么看都是进四退一

这个式引用过去的题目，我现在将题目格式修改了一下

上面是n=0结果 似乎不是1/2
