This document summarizes a simple dice game where a player pays $100 to roll two dice. The sum of the dice corresponds to a payout amount in a table. Though some outcomes pay more than $100, the game favors the house due to its odds. An analysis shows the average win is $30.56, so the game price is set at $40. While players may be attracted by higher potential payouts, the house maintains an advantage through its pricing.Game m

This document describes a dice game where players pay $50 per roll of two dice. Rolling a sum of 3 or 11 pays $100, while 2 or 12 pays $500. Otherwise, nothing is won. On average, players can expect to lose $11.11 due to the $50 cost to play offsetting the average $38.89 winnings. The standard deviation of wins and losses is $110.58. Videos of the game are also referenced.Game m

This game costs $50 per roll and involves rolling two dice. Rolling a 3 or 11 pays $100, while rolling a 2 or 12 pays $500. Otherwise nothing is paid out. Theoretically, players can expect to lose $11 on average per roll due to a mean win of $38.89 and the $50 cost to play. However, experimental results from a trial of 50 rolls showed the casino losing $1,400 total due to higher than expected wins of $500. The high variance in potential prizes makes it difficult to improve the game.CIII_FamilyFeud

The document describes a game where a player guesses whether a black or white die will have a higher outcome. They pay $5 to play and can win $5, $15, or $25 depending on the roll. Theoretical calculations show an expected payout of $4.17 per game, with the house making $0.83 on average. A simulation of 50 games found an average payout of $3.90, with the house making $1.10 per game. Both analyses found a standard deviation around $6. The game is slightly favorable to the house based on the theoretical calculation and more so according to the simulation results.Game e

This document describes a dice game called "Two is Company, Four is Money". Players roll 4 dice and earn money based on the number of fours rolled: $0 for 0 fours, $5 for 1 four, $15 for 2 fours, $25 for 3 fours, and $50 for 4 fours. Theoretical calculations show the average payout per game should be $4.08, with average deviation of $5.49 from the mean. A simulation of 50 rolls found average payout of $4.3 per game, meaning a $0.7 profit for the house given the $5 buy-in. While the simulation results closely matched the theoretical probabilities, the game overly favors theSt. Vincent de Paul Y5 Home learning W3 18.1.21 mon

The document describes a dice game where a player pays $25 to roll two dice. If they roll a sum of 2, 3, or 8 they win $175, $125, or $50 respectively. Otherwise they lose the $25. Theoretically, the expected value is a $6.25 loss for the player on average, with a standard deviation of $41.41. A simulation of rolling dice 50 times found an expected loss of $6.00 per play and a standard deviation of $48.61, showing a similar house advantage of around 12% for the casino.Game s

The document describes a carnival game called the Wonder Wheel. Players pay $150 to spin the wheel and keep whatever amount of money they land on. Theoretically, the expected value is a $8.13 loss for players and a $8.13 gain for the casino. Experimentally, the expected value is a $6.80 loss for players and a $6.80 gain for the casino. Both theoretical and experimental standard deviations are around $30-35, meaning the amount won or lost varies by that amount on average. The conclusion is that this could be a successful casino game due to large potential wins attracting players, while the house maintains an advantage due to the negative expected value.Decision decision decision

The document describes a game called Lucky Double Digits where players roll two dice and their winnings are determined by the sum. Theoretically, the expected value is $4.23 per game but the standard deviation is high at $6.65. A simulation of 50 games was conducted where the average payout was $6.08, meaning the house lost $1.08 on average per game. However, due to the law of large numbers, fluctuations in individual games would cancel out over many players. While modifications could give the house more advantage, it would likely decrease interest in the game. Therefore, the game would still be viable despite the house losing money in this simulation.Game ii

If the player's card has a higher value, they win $200. If it is lower or a tie, they win nothing. Drawing two aces yields $400 for the player. Theoretical statistics show the casino expects to win $3.55 per game on average with a standard deviation of $48.78.

There are three key steps to solving this problem:
1. Sammy started with x flavors and threw out y flavors, so he now has x - y flavors remaining.
2. To create combinations, we use the formula nCr = n!/(r!(n-r)!). Where n is the number of total flavors and r is the number we are combining.
3. Since we want 10-flavor combinations, and we know the number of flavors remaining is x - y, we can plug this value into the formula in place of n.
The key information needed is the original number of flavors (x) and the number thrown out (y) to determine the number remaining for combinations.Integerjeopardy

1) The document outlines an experiment to test the effects of different genres of music (classic rock, country, classical) on the aggression levels of lions.
2) Lions will be captured from different regions of Africa and tested individually in an enclosure. Their aggression levels will be rated on a scale before and after exposure to one song from a randomly assigned music genre.
3) The results will be analyzed separately for male and female lions, with the goal of determining whether music reduces aggression and, if so, which genre is most effective. Blocking and blinding techniques will be used to control for bias.Grou qq

The document describes a proposed experiment to study the effects of waiting different lengths of time after eating before swimming. It would involve 300 volunteers randomized into age groups and waiting times of 15, 30, or 60 minutes after eating before swimming. The response variable measured would be whether the volunteers get sick or experience cramps. Controls, randomization, and replication are used to reduce bias and variability. Factors like allergies, swimming style, and pain tolerance could also influence the results.Group n

This document describes a study designed to determine if eating before swimming causes cramps in children ages 6-10. The study uses a matched pairs experimental design. It will involve 3,500 students from 7 elementary schools, with 500 kids selected from each school evenly distributed across grades 1-5. The kids will be blocked by grade and gender then randomly assigned to eat a cheeseburger or have no food before a hour of swimming. They will record if they experience cramps. The experiment will be repeated with each child receiving both treatments on different days to directly compare the effects of eating vs not eating before swimming. Concerns about differences in activity levels, swimming ability, metabolism and pain tolerance between children are noted.Group dd

This study aims to determine if sugar makes kids hyper by testing 200 children ages 5-12. The children will be randomly assigned to receive either a beverage with 10 teaspoons of sugar or a sugar-free drink. Trained professionals will rate the children's hyperactivity levels before and after consumption. In a randomized block design, 50 boys and 50 girls will be split into two groups, with one group receiving sugar the first week and the other receiving it the second week, to control for gender differences and avoid carryover effects. The study employs double-blinding by not revealing to children or evaluators which treatment was received. Results will be analyzed to see if sugar increases hyperactivity ratings.Group q

This document outlines an experiment to test the "5 second rule" by dropping different types of food (grapes, carrots, chicken) onto either a hardwood or carpeted floor from 1 foot above. The food will be randomly assigned to the floor types and tested for bacteria compared to a control group of undropped food. There will be 50 pieces of each food split into two groups of 25 to be dropped, with one group going on hardwood and the other on carpet. The experiment aims to see if the floor type affects the amount of dirt or bacteria picked up by the food within 5 seconds of being dropped.Group pp

This document outlines an experimental design to test if oat bran reduces cholesterol. 1000 volunteers will be randomly assigned to eat either real oat bran or a placebo daily for 3 months. Their cholesterol levels will be measured before and after to see if those eating real oat bran experience greater reductions. Variables like diet, exercise, and medications will be controlled to isolate the effect of oat bran. Statistical analysis will compare cholesterol changes between the two groups and identify any trends in the data. The goal is to determine conclusively if oat bran lowers cholesterol when confounding variables are controlled.Group p

This study aims to test the hypothesis that shaving hair causes it to grow back thicker. It will involve 150 volunteers divided into two age groups. Volunteers will be randomly assigned to shave their arms and legs once, shave twice, or not shave at all. Hair thickness will be measured before and after using cluster samples. Blocking volunteers by age controls for natural differences in hair growth. The results will show if shaving leads to higher hair concentration when it regrows. Possible errors include volunteers not properly following the shaving treatment.Group oo

The document describes a proposed experiment to test whether spicy foods cause ulcers. It would involve randomly assigning 600,000 volunteers to eat either spicy or non-spicy meals for 3 months. The volunteers would be blocked into groups by race (Asian, African American, Caucasian) to see if race impacts results. After 3 months, each person would be checked for ulcers. The experiment aims to control for factors like race through blocking and uses random assignment and a large sample size for replication. However, it cannot fully account for individual ulcer risks or ensure participants follow their assigned diets.Group o

This study examines whether eating oat bran reduces cholesterol levels. It involves 100 American males aged 30-70, split into groups of 50 with high cholesterol and 50 with healthy levels. The men are randomly assigned to eat either meals with 3 servings of oat bran per day or meals with 0 servings for two weeks. Their cholesterol is measured after two weeks and two months later after switching diets. The study uses blocking by separating the groups and blinding by not informing subjects about the oat bran to reduce bias in results. A concern is other lifestyle factors may affect cholesterol without the researchers' knowledge.Group nn

The document describes an experiment to test if toads cause warts. It involves dividing 300 young people who have never had warts into 3 groups. Group 1 would hold toads for 5 minutes, Group 2 for 3 minutes, and Group 3 would not touch toads. The presence of warts after the experiment would be the response variable. Random assignment, blocking by gender, and blinding the participants about the real purpose would help make the experiment more reliable. However, concerns include upsetting participants if they develop warts, and difficulty finding people willing to hold toads. The conclusion is that this experimental design does not support the theory that toads cause warts, as no warts appeared in any participants.Group mm

This document outlines a proposed experiment to test whether eating chocolate causes acne. The experiment would involve 5000 teenage volunteers between ages 13-19, with 2500 males and 2500 females. Participants would be randomly assigned to eat either real chocolate or a placebo chocolate daily for 30 days. Before and after the trial, evaluators would rank each participant's acne severity from 1 to 10. The results would be analyzed by comparing acne rankings before and after to determine if real chocolate caused more acne than the placebo. If real chocolate resulted in significantly worse acne, it would indicate chocolate does cause acne.Group ll
