#32#

Explanation:

This can be solved using probability. Think about it like this. A coin has only 2 sides, heads and tails.

If the coin is being flipped #64# times, and you are trying to figure out how many times you get tails. If there is only one other side then tails, you can do the equation #64-:2#, to equal #32#.
