# Just Don't Drink In 3-Dimensional Space

A drunkard walks out of a bar at midnight. He is in 3-dimensional space of an infinite size. The probability of his stepping 1 step forward, backward, left, right, up or down is equal. Calculate the probability (to two decimal places) of his (eventually) returning to the bar.

Details and Assumptions:

• Assume the bar is a point particle at the origin.

• We require the probability that he will, at any point in time, return to the bar.

• Do not try this at home.
