A Man may take a step forward,backward , left or right with equal probability. Find the probability that after nine steps he will be just one step away from his initial position.
Pls don't post any more answers taking only the cases of forward and backward!!!! 
@akhil It is not necessary that he should move 4 steps and then come back . he can just move 1 step , then come back 1 step , again go 1 step , come back 1 step , etc.
