Introduction
Funds are tight but the graduating seniors want to have a special
senior trip. In this WebQuest, students will design their
own Keno Lounge. Students will learn the rules for Keno,
design payout cards for the game, calculate the return, and
prepare props for the lounge. Students will use probability
calculations to determine the return and payout for each game
which supports the following NCTM standard:
NCTM Principles and Standards for School Mathematics, Standard 5,
Data Analysis and Probability, grades 9-12: Instructional
programs should enable all students to understand and apply basic
concepts of probability -
The Task
The purpose of this project is for high school students to
be able to calculate probability for a Keno game. Students
will learn a practical application of a mathematics concept and
learn why casinos are so profitable. Keno is a good choice
for this exercise since it is a fairly easy game to understand
and model. Also, it is similar to the games used by many
state lotteries.
Students will have completed the probability unit in the textbook before this project is assigned. When this unit is complete, they will be able to apply probability calculations to other forms of gambling and learn why gambling is such a profitable enterprise. Students will be able to apply this information to most state lottery games.
This project will make calculating probabilities of numbers more exciting. Students have heard of several casino games and will enjoy learning how they are played and the chances of being able to win while playing these games.
After this project, students with skills in C++ programming
can write modeling simulations of Keno games. The computer
can simulate 1,000 cards of Keno and indicate the profitability
of the house or customer. "The Wizard of Odds" is
willing to write this software simulation for a fee for people
who are convinced that they have the perfect system for selecting
numbers. The Wizard has promised he will pay $20,000 to
anyone that can find a profitable betting system but he has not
paid anyone yet.
The Process
1. Students will form teams of four for this project for
steps 2 and 3. Steps 4 and 5 will involve the entire
class. Students are NOT to play any internet gambling games
during this learning experience - even free games.
2. Students will learn the rules and history of Keno by
accessing these websites:
Keno History http://www.keno-info.com/keno_history.html

Keno terms http://www.123keno.com/www/terms.htm
3. Students will learn how to calculate probabilities of a
catch. Payout rates will be selected and returns
calculated. These websites may be accessed for leaning how
to calculate probabilities and returns. A chart on this
Keno Appendix 3 are the probabilities and returns for basic keno
at the Atlantic City Tropicana. Students may want to
decrease the return to increase lounge profits for the
fundraiser. Each team will have their own payout sheet and
can operate as a separate casino.

4. Students need to construct a Keno form and make
copies. Students need to make number balls or blocks
labeled 1-80.
5. Students may want to serve "mocktails" and
snacks during the Keno game as an additional fundraiser.
6. Parents and friends are invited for an evening of fun
at the "Keno Lounge."

Evaluation
Students will conduct the "Keno Lounge" on a Friday
evening. Monopoly style money will be used in place of
real money to start each customer with $200. Each team or
casino will operate a ticket window for each round and will use
their own payout charts they constructed as a team. To
reduce confusion, a single ball machine will be used and numbers
will be generated at regular intervals. At the end of the
evening, customers and casinos will calculate their wins and
losses. Casinos with the lower returns should generate more
revenue.
In class the following Monday, the teacher and students will
discuss the profits and losses of the casinos and
customers. Students will write a one-page essay comparing
actual results with their hypothesis.
Conclusion
In this project, students learned how to calculate
probabilities and returns for Keno cards. Students should
have learned why casinos are profitable and why there is risk in
simple gambling games. Students can read the following site
for warnings about the realities of gambling:
