The owner expects that you hand wash each coffee pot before the coffee shop opens. you spend 72 minutes cleaning the coffee pots. it takes you 4 ½ minutes to clean a coffee pot. how many coffee pots are there?

You would do this: 72 divided by 4 1/2.
The answer should be: 16 I believe...

Hello!

there is no specific expected value, but I predict that is is going to be in the negatives.

a player is able to gain a total of 12 dollars, but has a HIGH probability of making less than they spent. If they had to pay $6, they would have a 50/50 chance of making their money back.
so no it is not a fair game either.

I hope this helps, and have a nice day!
