Hi forum, i'm new here, and have a burning question, that I can't seem to figure out or find on the internet.(adsbygoogle = window.adsbygoogle || []).push({});

If, for example, I've been told that I have a fair coin, and have 4 heads, what is the expected number of coin flips? of course, I assume it's 8 tosses, BUT what I really need to know is how to build the probability distribution over all number of flips N.

That is, in general, given H heads, and coin with probability of heads P, what is the probability distribution over N flips?

thx you for your time,

veritas
