Probability Puzzle Simulation

You play a game with a friend where he chooses two random numbers between 0 and 1. Next you choose a random number between 0 and 1. If your number falls between the prior two numbers you win. What is the probability that you would win? The applet below shows a simulation of this game. Each dot represents the proportion of wins in 200 games.
