I would like the final answer to be independent of the number but it's ok to start with a fixed number. I would prefer larger numbers if that matters because I am going to use this formula for N->∞

Maybe I didn't use the correct words but English is not my first language 
What I am asking for is the answer for the first statement (it's a different probability than tongzilla's and I think that it is easier to solve).
Sorry if I confused you with the second statement...

Hi,
I spent a couple of days looking for the answer for the above problem, so I would be very grateful to anyone who can help me with this one:
Consider a row of N unbiased coins. You can choose randomly one of these coins. What is the probability that this coin belongs to a run of L heads (or tails)?
In other words I want to know the probability that a coin belongs to a run of exactly L consecutive heads (or tails) in N independent tosses of a coin.
Thank you in advance for your help...
