Exercises 31 through 34 refer to a variation of the chaos game. In this game you start with a square ABCD with sides of length 27 as shown in Fig. 12-41 and a fair die that you will roll many times. When you roll a 1, choose vertex A; when you roll a 2, choose vertex B; when you roll a 3, choose vertex C; and when you roll a 4 choose vertex D. (When you roll a 5 or a 6, disregard the roll and roll again.) A sequence of rolls will generate a sequence of points
• Start. Roll the die. Mark the chosen vertex and call it
• Step 1. Roll the die again. From
• Steps 2, 3, etc. Each time you roll the die, mark the point two-thirds of the way between the previous point and the chosen vertex.

a. the sequence of rolls 2, 2, 4, 4.
b. the sequence of rolls 2, 3, 4, 1.
c. the sequence of rolls 1, 3, 4, 1.

- The game of Chomp is played by two players. In this game, cookies are laid out on a rectangular grid. The cookie in the top left position is poisoned. The two players take turns making moves; at each move, a player is required to eat a remaining cookie, together with all cookies to the right and/or below (that is all the remaining cookies in the rectangle, in which the first cookie eaten is the top left corner). The loser is the player who has no choice but to eat the poisoned cookie. Prove that if the board is square (and bigger than 1 × 1) then the first player has a winning strategy.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_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
- The game of craps is played with two dice. The player rolls both dice and wins immediately if the outcome (the sum of the faces) is 7 or 11. If the outcome is 2, 3, or 12, the player loses immediately. If he rolls any other outcome, he continues to throw the dice until he either wins by repeating the first outcome or loses by rolling a 7.arrow_forwardMickey and Minnie are playing a game. They spin a spinner that has 11 equally sized pieces, 3 red, 2 blue, 1 green and 5 yellow. If the spinner lands on yellow, Minnie wins $7. If it lands on blue, Minnie wins $ 4. If it lands on any other section, Minnie loses money. In order for the game to be fair, Minnie must lose $ Blank 1. Calculate the answer by read surrounding text. ifarrow_forwardAn archery target consists of a gold circle with radius of 5 inches surrounded by a red ring whose diameter is 20 inches. Next, there are three progressively larger rings – blue, black, and white. The diameter of each ring is 10 inches larger than the diameter of the previous ring. John is a beginner so his aim is poor and, if his arrow hits the target, its location on the target is completely at random. John shoots and then yells, “I hit it!” Without using your calculator, find the following probabilities. Write the answers as a percentage. a) The probability his arrow landed in the gold circle is ______. b) The probability his arrow landed in the white area is ______. c) The probability his arrow landed in the red or the blue area is ______.arrow_forward
- You are going to play the 7-11 game, which has the following rules: You roll two dice. If the total value of the two dice is 7 or 11, you immediately win the game. If the total value is 2, 3, or 12, you immediately lose. If the total value is 4, 5, 6, 8, 9, or 10, you keep this value as a referenced point. Then, you continue rolling the dice until you obtain the same value as the referenced point then you win the game. However, if you obtain the value of 7 before the referenced point, then you lose. For example, you obtain 4 in the first time of rolling, you keep rolling the dice until you get 4 (before 7) then you win. Similarly, you obtain 4 in the first time of rolling, you keep rolling the dice but you get 7 (before 4) then you lose. What is the probability to win this game? You can solve this question either by - a simulation - in this case you have to answer one more question, i.e., on average how many times do you roll the dice for each game?

The first phase is called the 'come out' phase, and the second is called the 'point' phase. If the 'come out' roll of 2, 3, or 12, the shooter loses. If the 'come out' roll is a 7 or 11 , the shooter wins. Otherwise, the game progresses to the 'point' phase. Complete parts (a) through (c) below. (a) What is the probability that the players loses? (Type an integer or a simplified fraction.) (b) What is the probability that the player wins? (Type an integer or a simplified fraction.) (c) What is the probability that the player progresses to the 'point' phase?

The amount to pay to play is P12. The prizes for each color are as follows: Red, Blue, P5 Yellow 31-35. Is the game fair? Show your computation to support your claim. P15 Purple, Orange.

The number that he gets is put aside as the "Target value". Then player two throws another die three times while giving player 1 information on weather he gets a lesser number than the target, equal to the target or greater than the target. Imagine that you are player one and you are handed the information that player two got [Lesser, equal, greater]. Deduce the probabilities of each possible target given the information.arrow_forward
