Concept explainers
In this version of “dice blackjack,” you toss a single die repeatedly and add up the sum of your dice tosses. Your goal is to come as close as possible to a total of 7 without going over. You may stop at any time. If your total is 8 or more, you lose. If your total is 7 or less, the “house” then tosses the die repeatedly. The house stops as soon as its total is 4 or more. If the house totals 8 or more, you win. Otherwise, the higher total wins. If there is a tie, the house wins. Consider the following strategies:
- Keep tossing until your total is 3 or more.
- Keep tossing until your total is 4 or more.
- Keep tossing until your total is 5 or more.
- Keep tossing until your total is 6 or more.
- Keep tossing until your total is 7 or more.
For example, suppose you keep tossing until your total is 4 or more. Here are some examples of how the game might go:
- You toss a 2 and then a 3 and stop for total of 5. The house tosses a 3 and then a 2. You lose because a tie goes to the house.
- You toss a 3 and then a 6. You lose.
- You toss a 6 and stop. The house tosses a 3 and then a 2. You win.
- You toss a 3 and then a 4 for total of 7. The house tosses a 3 and then a 5. You win.
Note that only 4 tosses need to be generated for the house, but more tosses might need to be generated for you, depending on your strategy. Develop a simulation and run it for at least 1000 iterations for each of the strategies listed previously. For each strategy, what are the two values so that you are 95% sure that your probability of winning is between these two values? Which of the five strategies appears to be best?

- You now have 5000. You will toss a fair coin four times. Before each toss you can bet any amount of your money (including none) on the outcome of the toss. If heads comes up, you win the amount you bet. If tails comes up, you lose the amount you bet. Your goal is to reach 15,000. It turns out that you can maximize your chance of reaching 15,000 by betting either the money you have on hand or 15,000 minus the money you have on hand, whichever is smaller. Use simulation to estimate the probability that you will reach your goal with this betting strategy.arrow_forwardThe game of Chuck-a-Luck is played as follows: You pick a number between 1 and 6 and toss three dice. If your number does not appear, you lose 1. If your number appears x times, you win x. On the average, use simulation to find the average amount of money you will win or lose on each play of the game.arrow_forwardYou have 5 and your opponent has 10. You flip a fair coin and if heads comes up, your opponent pays you 1. If tails comes up, you pay your opponent 1. The game is finished when one player has all the money or after 100 tosses, whichever comes first. Use simulation to estimate the probability that you end up with all the money and the probability that neither of you goes broke in 100 tosses.arrow_forward
- Consider the following card game. The player and dealer each receive a card from a 52-card deck. At the end of the game the player with the highest card wins; a tie goes to the dealer. (You can assume that Aces count 1, Jacks 11, Queens 12, and Kings 13.) After the player receives his card, he keeps the card if it is 7 or higher. If the player does not keep the card, the player and dealer swap cards. Then the dealer keeps his current card (which might be the players original card) if it is 9 or higher. If the dealer does not keep his card, he draws another card. Use simulation with at least 1000 iterations to estimate the probability that the player wins. (Hint: See the file Sampling Without Replacement.xlsx, one of the example files, to see a clever way of simulating cards from a deck so that the Same card is never dealt more than once.)arrow_forwardA martingale betting strategy works as follows. You begin with a certain amount of money and repeatedly play a game in which you have a 40% chance of winning any bet. In the first game, you bet 1. From then on, every time you win a bet, you bet 1 the next time. Each time you lose, you double your previous bet. Currently you have 63. Assuming you have unlimited credit, so that you can bet more money than you have, use simulation to estimate the profit or loss you will have after playing the game 50 times.arrow_forwardYou now have 10,000, all of which is invested in a sports team. Each year there is a 60% chance that the value of the team will increase by 60% and a 40% chance that the value of the team will decrease by 60%. Estimate the mean and median value of your investment after 50 years. Explain the large difference between the estimated mean and median.arrow_forward
- Based on Kelly (1956). You currently have 100. Each week you can invest any amount of money you currently have in a risky investment. With probability 0.4, the amount you invest is tripled (e.g., if you invest 100, you increase your asset position by 300), and, with probability 0.6, the amount you invest is lost. Consider the following investment strategies: Each week, invest 10% of your money. Each week, invest 30% of your money. Each week, invest 50% of your money. Use @RISK to simulate 100 weeks of each strategy 1000 times. Which strategy appears to be best in terms of the maximum growth rate? (In general, if you can multiply your investment by M with probability p and lose your investment with probability q = 1 p, you should invest a fraction [p(M 1) q]/(M 1) of your money each week. This strategy maximizes the expected growth rate of your fortune and is known as the Kelly criterion.) (Hint: If an initial wealth of I dollars grows to F dollars in 100 weeks, the weekly growth rate, labeled r, satisfies F = (I + r)100, so that r = (F/I)1/100 1.)arrow_forwardA winner of the multi - state lotto won a one-time payout and decided to invest part of it into an annuity. If the winner invests $6, 700,000.00 into a 30 year annuity that pays 3.5%, compounded monthly and makes each month payments. What is the amount of each month payments? The payment would be $ . (Round to 2 decimal places.)arrow_forwardYou are attempting to establish the utility that your boss assigns to a payoff of $1,000. You have established that the utility for a payoff of $0 is zero and the utility for a payoff of $10,000 is one. Your boss has just told you that they would be indifferent between a payoff of $1,000 and a lottery which has a payoff of $10,000 where the probability of losing is 0.7. What is your boss' utility for $1,000? (Round your answer to 1 decimal place.) Utility of $1,000arrow_forward
- Player A and B play a game in which each has three coins, a 5p, 10p and a 20p. Each selects a coin without the knowledge of the other’s choice. If the sum of the coins is an odd amount, then A wins B’s coin. But, if the sum is even, then B wins A’s coin. Find the best strategy for each player and the values of the game.arrow_forwardProblem Solving. The JSM company has been approached by an individual who has an idea for a new product. He wants to sell this idea for P32, 000. If the idea is purchased, the product must be developed. The company can develop the product at a cost of P64,000, and there is a 50% chance that they can develop the product. TMJ INDUSTRY has offered to develop the product. It will also cost P65,000, but they are only 40% certain that they can develop the product. No charge will be levied unless the job is successful. If the product is developed, it must be advertised. There are two plans for the advertisement. Plan A which costs P55,000 with 75% chances of success and Plan B which cost P38,000 with a 50% probability of success. The management believes that if the product is a success, the return will be P50 million. a) Should JSM purchase the idea?b.) who should develop the product?c.) which plan of advertisement should be adopted?arrow_forwardThe length of time between breakdowns of an essential piece of equipment is important in the decision of the use of auxiliary equipment. An engineer thinks that the best “model” for time between breakdowns of a generator is the exponential distribution with a mean of 15 days. If the generator has just broken down, what is the probability that it will break down in the next 12 to 24 days?arrow_forward
