If an action can be performed in X1 ways, and for each of these ways another action can be performed in X2 ways, then the two actions can be performed together in X1X2 ways. This is only if you don't have restrictions.
Restriction:A set of rules of what you cant use or do to find your set of how many ways.
Examples:
1.Kasy has 3 white shirts, 5 jackets, and 4 jeans. How many different outfits would she be able to wear?
In order to find out the correct answer you have to mulitiply three,five,and four all together and that will give you the total amount of outfits.
3x5x4=60 outfits
2.Mike is hungry and wants to make a sandwich. They have turkey,smoked ham,or baloney to choose from and he can have mustard,mayo,or ketchup with wheat,white,or brown wheat bread. How many different way can he make his sandwhich?
In order to solve this you will have to multiply the total amount of meat,components,and breads all together.
3x3x3=27 ways
