Counting Methods: Combinations by Formula and TI30XIIS Calculator

This is a detailed lecture that defines and explains combinations. The video includes the use of factorial formulas to find nPr and nCr as well as an explanation of how to use the TI30XIIS calculator for this purpose. The video gives tips on when to use Combinations, Permutations, or the Fundamental Counting Principle and shows an example where more than one counting method is used.

This video helped me understand hoe to find factorial formulas using PRB and nCr using the calulator

In this video I have learned how to use the calculator to calculate combinations. and I'm learning to count again! (: )

I'm interested in Mathematics.
Can I do my PhD under your guidance ?

"To calculate permutation, one way is to start with the number of objects and to multiply three factors together reducing by one each time"

"the most important thing is the clue words that are going to tell you whether you have a combination or permutation"

When counting problems, subsets, where order of elements makes no difference, it is often called combinations.

I learned that a subset has no particular order of the elements.

"For Permutations you're arranging objects and they're unique objects so repetition is never allowed"
