One of the games in the Texas lottery is to pay $1 to select a 3-digit number. Every Wednesday evening, the lottery commission randomly places a set of 10 balls numbered 0 - 9 in each of three containers. After a complete mixing of the balls, 1 ball is selected from each container.
a. Suppose you purchase a lottery ticket. What is the probability that your 3-digit number will be the winning number?
b. Which of the probability approaches (subjective, classical, or relative frequency) did you employ in obtaining your answer in part (a)?
