Probability Teaser #28
I have a CD with 10 tracks on it. I like to play it with my stereo set on shuffle. The way my stereo works is that it will play all 10 songs in a random order without repeating any of them. Then, if I let it keep going, my stereo will play all 10 songs again in a different random order. Using this method, it is possible that my stereo could play the same song twice in a row. What is that probability?
