Default Re: Am I using this ROR Formula Correctly?

[ QUOTE ]
Right , stupid me .

Any multiple of 10 works.

r=0.5 + [0.5^10r^11 + 0.5^20r^21 + 0.5^30r^31+...]

Notice that [..] is a geometric infinite series with
a=0.5^10r^11
ratio= 0.5^10r^10

NO, it's still no good. You are only considering the highly unlikely cases where he wins multiples of 10 in a row, and ignoring the primary cases such as winning less than 10 games and losing 1 more than he wins.
