Fundemental Counting Principle

Hello, so today we had another sub in the class, Mr. Penner. We were assigned "Exercise 2: Counting Principles" for the day. A reminder that the answer key to check your answers can be found on the coursework drive.

Yesterday in class we were to finish all pathways problems from the had out we received, and then teach ourselves the Fundemental Counting Principle.

Incase you were unable to finish the second half of the assignment, I will briefly describe it to you in the post.

The Fundemental Counting Principle

When two or more choices must be made together, the total number of outcomes can be determined without listing and counting them. The rule for this is known as "The Fundamental Counting Principle."The Fundamental Counting Principle states the following: If one event can occur in 'a' ways, a second event in 'b' ways, a third event in 'c' ways, and so on, then the number of ways that all events can occur one after the other is the product a*b*c. . .

ex. Sue has four pairs of shoes, five pairs of jeans, and seven sweaters. How many different clothing combinations can she select?

So you take the number of shoes, multiplied by the number of jeans, and multibly that by the number of sweaters.

4*5*7 = 140

The number of ways which Sue can dress is 140.

For more help on this or any other topic in the class always refer to the online course for help. Thats the end of my post, have a nice day!
