The Texas Lottery has a game, Daily 4, in which a player pays $ 1 to select four single-digit numbers. Each week the Lottery commission places a set of 10 balls numbered 0–9 in each of four containers. After the balls are thoroughly mixed, one ball is selected from each of the four containers. The winner is the player who matches all four numbers.
a. What is the probability of being the winning player if you purchase a single set of four numbers?
b. Which of the probability approaches (subjective, classical, or relative frequency) did you employ in obtaining your answer in part (a)?
