Pete, Re: "The exact formula for the probability of x number of heads over n tosses is (x!*(n-x)!)/(2^n). For more general case of
at least x heads, it is the sum from j=x to n of (j!*(n-j)!)/(2^n)."

Thanks! This is what I was computing in my spreadsheet but it didn't like numbers greater than about 10E+305 so I could only go up to n=1000 or so... and could determine the numerator up to n=1200 or so.

Regardless, the number is quite small.

Pete, Re: the exact term for the coin toss distribution curve is a "Binomial Distribution

Yes, exactly. I hope this clears up all confusion. Probability theory can really be a pain... ;-)
