Normally a discussion on probability or statistics begins with outcomes from an experiment, what we refer to as sample space

**Taken From CNX.org**A sample space is a set or collection of outcome of a particular random experiment.

For example, imagine a dart board. You are trying to find the probability of getting a bullseye. The dart board is the sample space. The probability of a dart hitting the dart board is 1.0. For another example, imagine rolling a six sided die. The sample space is {1, 2, 3, 4, 5, 6}.

**Examples of Sample Space**.- The tossing of a coin, sample space is {Heads, Tails}
- The roll of a die, sample space is {1, 2, 3, 4, 5, 6}
- The selection of a numbered ball (1-50) in an urn, sample space is {1, 2, 3, 4, 5, ...., 50}
- Percentage of calls dropped due to errors over a particular time period, sample space is {2%, 14%, 23%, ......}
- The time difference between two messages arriving at a message centre, sample space is {0, ...., infinity}
- The time difference between two different voice calls over a particular network, sample space is {0, ...., infinity}

Many educators use a tree diagram to help students understand outcomes which is a very handy tool.

(Flipping a Coin and Rolling A Die) |

Yet, even with a great tool like a tree diagram, there is still a disconnect between the teaching and the student. We need a better way to reach them!

I like this idea suggested by one of my statistics students!

**How Many Outfits Can I Wear?**

Using stickers of different clothing (shoes, hats, dresses, etc), let your students discover the amount of mixing and matching they can perform to create different outfits.
