Happy Holidays!!!

A short post to wish each of you the very best of the holiday season! Take some time over the next couple of weeks to relax, revive, and refresh, because before we know it, the provincial exam will be staring us down...But don't think about it again until after Christmas...


On that note, I've decided to post the links to the .pdf copies of the last couple of year's worth of provincial exams HERE.....For reference, you'll need to have Adobe Reader installed on the PC you're using to view/save the files, and on the link I've included, you can download and install easily from the bottom left side of the same page. Take it easy, see you January 2007....RM

Scribing Pods

As of today,
4 pods each of students ...so that I can do a better job of managing who is scribing on a day to day basis...I'll keep using the red, tiny, italicized notation for posting who has scribed.......

Pod #1

My last observation is that our class scribe list is still missing a Melissa, a Tori and a Seth....Where are you guys?? You're losing marks when you're not a contributor...

Permutations and Combinations

Or, “Perms and Coms” for those of us who love simple terms.

Consider the letters, A, B, C, D, E

How many different “words” can we make using the FCP to solve this problem?

First thing you have to know is, ORDER MATTERS!!!!!!! In solving a PERMUTATION.

“ABCDE” is different from “ABCED”

and how do you find out how many “words” this is? Well, you go,

5 x 4 x 3 x 2 x 1

= 5!

=120 ways

But say we used the whole alphabet, what then?

26 x 25 x 24 x 23 x 22

=7,893,600 ways to permute 26 letters.

OR

26 letters permuted 5 at a time.

Hmm…. Or you could go…

(26 x 25 x 24 x 23 x 22) x 21!

21!

26!

21!

and voila! It = 7,893,600

or

nPr = “n things permuted r at a time”

= 26 letters permuted 5 @ a time.

The Calculator button presses to do this all the easy way are,

26 > Math button > PRB> nPr > 5 and Enter

n = total # of elements to draw from

r = How many elements at a time

Here is an example of permutation…

Remember, ORDER MATTERS!!!!

Say you have a security code with 4 digits, and there are no repeats.

You could go the long way and type in,

10 x 9 x 8 x 7

= 5040 ways

OR…

nPr……10 P 4 = 5040 ways.

Now onto COMBINATIONS

Examples in heart’s and diamonds’s.

How many different poker hands (5 card hand)

In a combination ORDER DOESN’T MATTER!!!!!

26 x 25 x 24 x 23 x 22

=7,893,600 NO!!!! But… THIS ISN’T THE RIGHT ANSWER…

You have to “Divide out the doubles.”

You should go,

(26 x 25 x 24 x 23 x 22)

5 x 4 x 3 x 2 x 1

= 65,780

nCr = n!

(n-r)!-r! <<>

basically, 26!

(26-5)!-5!

= 26!

21! – 5!

= 65780

26 C 5

26 cards Chosen 5 @ a time where order DOESN’T matter!
26 – math – nCr- 5

= 65780

Combinations end up with a smaller result number.

Permutations end up with much larger result numbers.
