Textbook Question
Chapter 8.5, Problem 18E
Suppose one day Mary brings a 2-headed coin and uses it to toss for the coffee. Since Mary tosses, Donna calls.
- (a) Is this still a fair game?
- (b) What is Donna’s expected payback if she calls heads?
- (c) What is Donna’s expected pay back .if she calls tails?
EXAMPLE 5 Friendly Wager
Each clay Donna and Mary loss a coin lo see who buys coffee ($1.20 a cup). One tosses and the other calls the outcome. If the person who calls the outcome is correct. the other buys the coffee, otherwise the caller pays. Find Donna’s expected payback.

You play a game where you roll two dice. It was decided that you lose ₱500 if you get a sum of 3, 6, or 9, and you lose ₱400 if you get a sum of 10. However, you win ₱300 for anything else. If you continue to play the game, how much do you expect to win or lose in the game in the long run?
you are playing a game in which a single die is rolled. if a 2 or a 5 comes up, you win $24, otherwise you lose $3. what is the price that you should pay to play game that would make the game fair?
Introduction: Here's the game: there are two boxes with four balls each. To play, you put on a
blindfold and then pick one ball at random from each box.
There are two red, one blue and one green ball in the box on the left. There are two blue, one red
and one green ball in the box on the right.
Payouts:
• So if the balls are different colors,
• S0.50 if they are both red,
• Sl if they are both blue, and
• $16 if they are both green.
Question:
If the game costs $1 to play, would you expect to gain or lose money on average? And how
much?
In your solution, you must show:
• How you compute the probability that payout is $0.
• How you compute the probability that payout is $0.50.
• How you compute the probability that payout is S1.
• How you compute the probability that payout is $16.
Summarize the data into a probability table.
• Compute the expected value.
Remember to account for the $1 you pay to play the game.
• Your conclusion.

So did my family. One evening, my family played a game that heavily relied on luck. Imagine we played a game that used rolling six-sided dice (as in the game Monopoly) and the outcome of ones turn was based on the result of rolling the dice. My son made three bad rolls in a row and yelled “This is unfair!". Elaborate whether he was right or wrong with his statement.. Use only what we discussed about fairness in this lecture.arrow_forward

- You have 80 dollars and play the following game. An urn contains two white balls and two black balls. You draw the balls out one at a time without replacement until all the balls are gone. On each draw, you bet half of your present fortune that you will draw a white ball. If you do, you win an amount equal to your bet. If you do not, you lose your bet. What is your expected final fortune? Gerolamo Cardano in his book, The Gambling Scholar, written in the early 1500s, considers the following carnival game. There are six dice. Each of the dice has five blank sides. The sixth side has a number between 1 and 6--a different number on each die. The six dice are rolled and the player wins a prize depending on the total of the numbers which turn up. Find, as Cardano did, the expected total without finding its distribution.arrow_forwardSuppose you decided to play a gambling game. In order to play the game there is a $1.50 dollar fee to play.
