You can observe the footsteps of a drunk man.
Drunk people wander indiscriminately from side to side. Drunk people often come back to the same place as they walk around to reach their destination.
Now suppose the drunkard is at the origin on the number line. Where is the drunkard on the number line when he starts from the origin and wanders 30 times?
However, it is assumed that a drunk man sways in only two directions, left and right, and moves only one with one sway. Also, suppose that there are half and half swaying to the left and swaying to the right.
Probability that the position on the number line when swaying 30 times is 0, probability that the position on the number line when swaying 30 times is 1, and probability that the position on the number line when swaying 30 times is 2. Let's find each mathematically.
