100 coins are lying flat on a table. 10 of them are heads up and 90 are tails up. How can we split the coins into two piles(eyes closed)such that there are same number of heads up in each pile?
(Not supposed to find the type of coin by feeling the impression)

There are many ways in which this could happen - because the only constraint is that each pile must have 5 heads. The possibilities range from one pile having 90 tails up coins to the same pile having 0 tails up coins.
