**bobpursley**, Friday, October 8, 2010 at 9:14pmThe important thing is that the probability of a grain of sand to be one one square is equal.

Pr(on a particular square)=1/64

So if we put a grain on any one square, the next 9 have to be on that next square. The probability of that is

Pr(10 on same square)=1*(1/64)^9

which is exceedingly small.
