Snack Combinations and Counting Principles

The video tutorial explains the addition and multiplication principles of counting. The addition principle involves adding the number of options when choosing between alternatives, while the multiplication principle involves multiplying the number of choices in a sequence of decisions. Examples include choosing ice cream flavors and scoops, and combining choices of ice cream and yogurt. The tutorial demonstrates how these principles can be applied to calculate the total number of possible outcomes.
