A fast food chain is running a promotion to try to increase sales. Each customer who purchases a meal combo receives a game piece that contains one of the letters U, W, I, or N. If a player collects one of all four letters, that player is the lucky winner of a free milkshake. Suppose that of all game pieces, 10% contain the letter U, 30% contain W, 30% contain I, and 30% contain N. Use the table of random digits to estimate the probability that you will collect enough game pieces with your next five combo meal purchases to receive the free shake. Clearly describe the steps of your simulation. Your simulation should consist of at least 20 repetitions.
