A subsequence of consecutive heads is called a run of heads. Consequently, the following sequence of length \(n = 20\): \begin{equation} HHTHTTHHHHTTTHHTTTTH \label{eq:tosses} \end{equation} contains 5 runs of heads with lengths 2,1,4,2,1, respectively. The longest run of heads is \(M_n = 4\). If we toss a coin 1000 times and get that the largest number of heads in a row was 6, is this a fair coin? https://silacos.netlify.app/blog/brain_teaser_series/probability/ Sat, 08 Sep 2018 00:00:00 +0000 https://silacos.netlify.app/blog/brain_teaser_series/probability/ Some brain teasers challenges I got, my take on them, and solution! 😃 Bet Coin Flips In A Row What is the maximum amount you are willing to pay in order to play this game?
