Match or No Match

questions
Act One

May 07, 2013
Is the next one a match or not? How many of each colour are in the bag? (When can I get a new camera?)
Act Two
 VideoAll the trials
 Teacher noteHere are a list of some of the questions students had during the trials:
When are you stopping?
How many yellows?
What's the probability after 20 tries?
What are the chances of a match?
What's the experimental probability?
What's the theoretical probability?
What's in the bag?
As you can see most questions lead to more questions or need some tweaking.
Final information needed to answer some of those questions:
100 trials = 57 nonmatches, 36 blue matches, 7 yellow matches
Act Three
Sequel
 1.
How far was the experimental probability from the theoretical probability?
 2.
What results would you predict for a bag with 4 blue and 3 yellow (after 100 trials)?
 3.
What contents of a bag would result in 50% matches and 50% nonmatches? Can you prove it experimentally, and/or theoretically?
 4.
Can you create a bag that will result in 25% matches theoretically?
 5.
Do you see a pattern in your theoretical results? For example a bag with 1 blue and 1 yellow, or (21), (31), (41) and so on.

What is are all the options that could be pulled out and what are their probabilities














Do you think the next pull will be a match or a non match? Which colors do you predict they will be if they do match?
