One night on a cold street in Copenhagen, a drunk walked by staggering left and right. Every 1 minute, the drunk changes direction and walks x meters to the left, or y meters to the right. The probability that the drunkard walks to the left is p (ie probability of walking right = 1-p). The drunk started walking from a bar where 200 meters to the left was a garden; and 200 meters to the right is the police station. A. Predict which way the drunkard is walking? Elaborate why drunkenness walk towards the park or the police station! B. Count how many meters is the drunkard's location after walking n minutes! C. If the drunk is about to fall asleep after walking for 1 hour, find out where the drunk is Sleep? has it passed the park/police station? Note: Take the last 3 digits of my ID. Use the steps below: 1. For example, ID 2602296545 → then what is taken is 545. 2. Change the number 0 to number 1; example: ID 545 → 145 3. From the new ID, take the largest and smallest digits; example: min _number = 1, max_number = 5 4. Drunk means walking x = min_number to the left; and y = max_number to right; with probability p = (min+max) / 20 to the left. example: walk 1 meter to the left; and 5 meters to the right; with probability p=0.5 to the left
