Ram is attending a disco party. Upon arriving, each of the K party members including ram puts his or her coat on the coatrack. After party, the first person to leave grabs a coat at random from the coatrack. As the rest of the members leave, they try to grab their own coat, but if their coat has already been taken, they take someone else's coat at random from the rack. Ram is the last person to leave the party. What is the probability that ram will go home with his own coat?
