I am trying to establish correlation between tossing of coins and occurring of repeats.

Coin is flipped 10 time as follows:

$${\rm H.T.H.H.H.T.H.T.T.T. }$$

After each repeat occurring I have put (R) as follows:

$$ {\rm H.T.H.H(R).H(R).T.H.T.T(R).T(R). } $$

So in this exercise I have 4 repeats, any patteren/symmetry/correlation could be estblised here?

Is it fair to conclude in 10 toss I get 4 repeats and establish for 12th or 13th flip repeat is certain?

    *Certainty* is not achievable. It is possible, though highly unlikely, that the first $50$ tosses will monotonously alternate between H and T. But information about the distribution of the number of repeats is obtainable, and information about the *mean* number of repeats in say $10$ tosses (or $n$ tosses) tosses is easy to get. The mean number of repeats in $10$ tosses is $4.5$.2012-04-07

    Thanks Andre, I have tried in Excel using random command for 2000 flips. The R was 969, Heads were 984 and Tails were 1016. Now is is possible to get clear picture?Thanks in advance Rodney2012-04-07
