a gift exchange

Ten friends organize a gift exchange. The ten names are put in a hat, and the first person draws one. If they pick their own name, they return it to the bag and draw again, until they have a name that is not their own. Then the second person draws, again returning their own name if they draw it. This continues down the line. What is the probability that when the 10th person draws, only their own name will be left in the bag?
any help!!!
