Essay
A rather harried father is trying to find a much sought after toy for his daughter for Christmas. He has a choice of 10 stores to go to. From a radio announcement, he learned that the toy can definitely be found at 4 of the ten stores. Unfortunately, he did not hear which four stores! If the store he stops at does not have the toy, he will leave without buying anything, in other words, there is no replacement. He only has time to go to three stores. What is the probability that he will find the toy at the first stop?
