Formula seems to be the same one I used, not sure how I got half the value?
Let's see,...yep, works out to 0.246. I should have checked my answer before hitting send, serves me right for rushing through a post where I was pointing out someone's mistake.
I assume you are familiar with using Pascal's triangle to solve these types of coin flip problems as well? It gets awkward with more than a handful of flips but it works beautifully. For ten flips it would yeild 252/1024 (which is four times the factorial result but of course yeilds the same quotient).
Don't worry about that, that was not the point anyways. We're talking about the method, the exact result is irrelevant.
The method for determining the number of heads or tails in any given number of tosses is based in statistical theory. The "odds" in this case are an "educated guess".
If someone tells you otherwise they are lying to you.
