发帖数: 53 | 1 This is an old problem. But I didn't figure out how to do it. So, 请大侠们
give a detail how to solve it, not just the answer.
Keep tossing one coin until either HHHT or HTHT shows up, What is the
probability of having HHHT
I am CS major, so, if you could provide some background material, thats
would be even more appreciated. | z****i
发帖数: 406 | 2 don't know whether I'm thinking it correct...
the probability is the same as that of having HH before HT, which is just 1/
2.
don't know whether there is a general method for this kind of problems,
waiting for big niu... | a****9
