Assume you're tossing a fair coin; you win only if you get (i+1) consecutive heads right after (i) consecutive tails; what is the probability this game never stops?

My attempt is as below: $P$(never stop)$=$$P$(1 T before 2H|1T)$*$$P$(1 T before 3H|1T)$*...=\prod_{n=1}^{\infty}(1-\frac{1}{2^{n+1}})$

However, could anyone verify my solution? Also, does $P$(never stop) converges to 0?

  • Do you want any $i$ or a particular $i$? Either way, the probability you never stop with a fair coin is indeed $0$ – Henry Aug 24 '22 at 15:01
