MATHEMATICS 2
M2.4: Probability
M2.4.C Permutations, Combinations, and Factorials
Introduction
These videos discuss permutations and factorials. The classes and textbooks from which they were developed is not ours, so please ignore the course names and chapter numbers. If you have difficulties with the videos, you may want to check the plug-ins for your browser.

Permutations, Combinations, and Probability
Let us look at permutations and factorials from the perspective of probability. Please download the PowerPoint presentation narrated by your instructor, Yvonne V. Richardson. The PowerPoint 2007 presentation should automatically play sound and video when the download is complete; if there are difficulties with the presenation, you may want to save the downloaded file, rather than open it. The presentation is in two different formats, so you can choose whichever one is best for you.

When you are done, right-click anywhere on the slide presentation, then select "End Show". The presentation will return to the calling application.
Exploration of Knowledge and Tools
When you have finished viewing these videos, please participate in the poll. When the number of votes indicates that everyone has reached this point, I will unlock the Probability Exploration Room so we can explore the topic as a group.
(Due to the nature of course design, for the moment the room is unlocked; please go to the Probability Exploration Room when you are done with the poll). When you return, please post the answers to your questions in the Probability Blog. When you post your answers, I will e-mail the homework assignment to you. |

Reflection and Revision
You will receive your homework assignment when you complete the exploration activities. Complete the following homework assignments individually by the due date listed on the Course Schedule. You can create Word documents, .txt files, .rtf files, .gifs, .jpgs, or .zip files that contain those formats; all other document formats will be rejected. Attach your e-mail to the homework assignment and return it to me at [email protected].
You are assigned to groups of 3 for the next exercise, by the second letter of your last name.

Assessment and Observation
Group Collaboration
For this competency goal, you have described equations using new terminology such as “combinatorial” and “factorial”. New tools for probability studies include the ability to refer to combinations as "n choose k" and the capacity to determine whether order matters before computing probability.
You have reinforced your knowledge with individual homework, so the next activity will assess your competency in groups of 3 to solve problems. You have a week for this exercise.
Group 1: Student, Student, Student (your name here)
