you don’t know which coins are heads or tails

you are blindfolded

you don’t know which one is a tail to flip…

]]>No. You have some number of coins. You know that 99 of the coins are heads, but you do not know which ones. You want to have two piles where the two piles have the same number of heads. By this, I mean heads face up.

]]>you don’t have a tails pile — you don’t know which is which, all mixed together

]]>I don’t see how that solves the problem. You need to say how many are in each pile and what you flip and when. Email to you bounced, you can email me at sjm1@williams.edu
