# Probability of finding at least k consecutive heads in N coin tosses?

There are quite a few topics on this question already but I couldn't find a well-explained solution. Please point me towards some relevant literature or theory to analyze this problem.

$K$ consecutive heads with a biased coin?

Probability of tossing a biased coin without having k heads consecutively in a row

Probability of tossing a fair coin with at least $k$ consecutive heads

Thanks.

I think this would be a duplicate except that you're asking for relevant literature or theory; as such I've added the reference-request tag. –  Goos Sep 12 '13 at 17:51
"I couldn't find a well-explained solution" Users Sasha and joriki will be delighted. (Unrelated: several other MSE pages answer the same question in details.) –  Did Sep 12 '13 at 17:59
