The St. Petersburg paradox. Here is an interesting game: You pay a certain amount of money to play. Then you flip a fair coin. If you see tails, you flip again, and the game continues until you see a head, which ends the game.
If you see heads on the first flip, you receive $2. If you see heads on the second flip, you receive $4. If you see heads on the third flip, you get $8, and so forth—the payoff is doubled every time. What is the expected payoff of this game? How much would you pay to play this game? Suppose you pay $1000 to play. What is the probability that you would make money? Why is this game a paradoxical situation given the expected value?

- Suppose you decided to play a gambling game. In order to play the game there is a $1.50 dollar fee to play. If you roll a 1, 2, or 3 you win nothing (i.e., your net profit is $-1.50). If you roll a 4 or 5, you win $3.50 (i.e., your net profit is $2.00). If you roll a 6 you win $5.00 (i.e., your net profit is $3.50).Use the information described above to construct a probability distribution table for the random variable xx which represents the net profit of your winnings. Note: Be sure to enter your probabilities as reduced fractions. Die Roll xx P(x) Roll a 1, 2, or 3 Roll a 4 or 5 Roll a 6 Find the amount you would expect to win or lose each time you played the game. Round your final answer to two decimal places.μ=arrow_forwardYou go to a casino and play a game. You throw a fair 4 sided die whose sides are labeled 1, 2, 3 and 4. If you land on a 1, you get $30. If you land on a 2, you get $10. If you land on either a 3 or a 4, you owe the casino $8. If you play this game repeatedly, what would your "winnings" be on average, in dollars?arrow_forwardYour friend proposes a game: You flip a coin. If it’s heads, you win $1. If it’s tails, youlose $1. However, you are worried the coin might not be fair coin. How could youchange the game to make the game fair, without replacing the coin?arrow_forward
- The game "craps" is played as follows: A player rolls two fair six-sided dice. If their sum is 7 or 11 the player wins right away. If their sum is 2,3, or 12, the player loses right away. If their sum is any other number, this number becomes the "point". The player then repeatedly rolls two dice until their sum equals the point, in which case the player wins, or equals 7, in which case the player loses. What is the probability of the player winning?arrow_forwardOne option in a roulette game is to bet $7 on red. (There are 18 red compartments, 18 black compartments, and two compartments that are neither red nor black.) If the ball lands on red, you get to keep the $7 you paid to play the game and you are awarded $7. If the ball lands elsewhere, you are awarded nothing and the $7 that you bet is collected. Complete parts (a) through (b) below. III a. What is the expected value for playing roulette if you bet $7 on red? $ (Round to the nearest cent.) b. What does this expected value mean? Choose the correct statement below. O A. This value represents the expected loss over the long run for each game played. OB. Over the long run, the player can exper to break even. OC. This value represents the expected win over the long run for each game played.arrow_forwardOne option in a roulette game is to bet $9 on red. (There are 18 red compartments, 18 black compartments, and two compartments that are neither red nor black.) If the ball lands on red, you get to keep the $9 you paid to play the game and you are awarded $9. If the ball lands elsewhere, you are awarded nothing and the $9 that you bet is collected.

- If I $6 to play a spinner game and the chances of winning $1 dollar is 50% and the chances of winning $12 is 50%. What is the fair price of the game?arrow_forwardYou are playing a game in which a single die is rolled. If a 2 or a 5 come up, you win $60; otherwise, you lose $3. What is the price that you should pay to play the game that would make the game fair?arrow_forwardA game involves tossing two coins and receiving 70¢ if they are both heads.

- you roll two standard dice. If you roll doubles, then you pay $5. If the game is fair, what would the house have to pay if you do not roll doubles?arrow_forwardYou are playing a game in which a single die is rolled. If a 2 or a 5 comes up, you win $60; otherwise, you lose $3. What is the price that you should pay to play the game that would make the game fair?arrow_forwardMike and Bill play a card game with a standard deck of 52 cards. Mike selects a card from a well-shuffled deck andreceives A dollars from Bill if the card selected is a diamond and receives $1 from Bill if the card selected is an ace that is not adiamond. Otherwise, Mike pays Bill two dollars. Determine the value of A if the game is to be fair.arrow_forward
