Problem 11
A token starts at the point of an
-coordinate grid and them makes a sequence of six moves. Each move is 1 unit in a direction parallel to one of the coordinate axes. Each move is selected randomly from the four possible directions and independently of the other moves. The probability the token ends at a point on the graph of
is
, where
and
are relatively prime positive integers. Find
.
