big money, and they use highly mathematical boards. The members each make their own board by placing 25 given numbers at random on a blank grid. The bingo caller pulls one number at a time from the golden bingo bucket. Here we see the board that Santa created last night. a.) What is the probability that the caller will pull a positive multiple of three?
b.) What are the chances that a negative number will be chosen?
c.) What % of chance is there that an irrational number will be drawn? (remember that irrational numbers are numbers that can't be written as fractions, they are non-repeating, non-terminating decimals like the square root of 7 and the number pi)
d.) What is the probability that a number divisible by 1000 will be called?
e.) What percent of chance is there that the caller will draw a Real Number?

There she was on the roof, throwing giant foam dice at the members of Dr. Miller's gym class. Onlookers reported that she screamed with joy every time a "turtle" was nailed. The gamblers in the crowd were figuring probabilities. |

Zack's House of Bagels is running another gambling, promotional, game
to try and boost sales. Let's see how it will work. The customers are given two dice when they make their order. If they roll two even numbers, they get a FREE large drink valued at $1.15. |
| a.) What is the probability that a customer will get a free drink? |
| b.) If the game brings in an extra 32 people for lunch because they think they can get a free drink, and they spend an average of $5.32, how much extra money will the store make from these people? |
| c.) If 384 people play the game at lunch time, how many free drinks will they probably have to give away? |
| d.) If the price of a large drink is $1.15, how much money will the store lose? |
| e.) This gambling game seems to be generating more money even though they give away free drinks. How much more money is being made at lunch time even after they figure in the loss on the drinks? |
|
f.) If this game runs for 30 days, and the results stay constant, how much extra income will be generated by the lunch crowd? |
