Can you elaborate? I don't understand this still. I do understand how the sum of all n choose k equals 2^n. That just ends up being the set of all subsets which has 2^n elements. What I don't understand is what the 1/2 probability has to do with deriving that formula.

@AndréNicolas Yeah I mean it is kind of obvious. I sort of said that to bait an explanation as to why. Can you elaborate?
