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 are 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. Download the PowerPoint presentation narrated by your instructor. It is in two different formats, so you can choose whichever one is best for you. The download process should save the file, and you should see the name of the downloaded file in the top right corner of your browser. You can click on it to begin viewing; it should automatically play sound and video. If there are difficulties with the presentation, you may want to save the downloaded file, previous to opening it.

When you are done,you can click the forward-arrow one more time, or right-click anywhere on the slide presentation, then select "End Show".  The presentation will return to the online classroom.

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, the room is unlocked, and you can go to the Probability Exploration Room when you are done with the poll).

When you return, post the answers to your questions in the Probability Blog. When you have posted, I will e-mail the homework assignment to you.

Reflection and Revision

You will receive your homework assignment when you complete the exploration activities.  For the next exercise, you are assigned to groups of 3, by the second letter of your last name.

Complete the following homework assignments individually by the due date listed on the Course Schedule. You can create Word documents, .pdfs, .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 yvonne.richardson@comcast.net. 


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 to complete this exercise.
