No, what I'm saying is that any given coin flip has 50% probability
coming up heads. However, you are talking about flipping a coin n
times, where you will get n-1 heads, and 1 tails, the probability for
this is much lower than for n/2 of each.
Actually, the formula I gave isn't totally correct. It works if you
don't care which order the flips come in. If we do care about order
(what's the probability that I will flip 9 heads and then 1 tail),
then the probability is simply .5^n.
The confusion comes from looking at individual flips versus a series of
flips.
