Concept explainers
Arizona and New York have Pick 3 games (New York's is called "Numbers"), as described in Exercises 19 and 20 of Section 3.4. If the player opts for "straight play" and wins, she wins $500 (but she pays $1 to play, so her profit is $499). If the player opts for "box play" with three different digits and wins, he wins $80. If the player opts for "box play" with two of the same digits and wins, he wins $160.
a. Use the probabilities from Exercises 19 and 20 of Section 3.4 to find the probability of losing.
b. Use the probabilities from part a and from Exercises 19 and 20 of Section 3.4 to find the expected value of the game.
