How many of you have trouble putting together an outfit each morning?
Lots of hands went up. In this example, students had to create “outfits” given 3 tops and 2 skirts. Many quickly realized the “Fundamental Counting Principle” what states if you take the number of outcomes of one event and multiply it by the number of outcomes of another event, you will get the number of all possible outcomes.
In this case 3 outcomes of shirts x 2 outcomes of skirts = 6 possible outcomes.
