Use the Fundamental Counting Principle to solve Exercises 29–40.An ice cream store sells two drinks (sodas or milk shakes) in four sizes (small, medium, large, or jumbo) and five flavors (vanilla, strawberry, chocolate, coffee, or pistachio). In how many ways can a customer order a drink?

The Fundamental Counting Principle states that if there are 'm' ways to do one thing and 'n' ways to do another, then there are m × n ways to perform both actions. This principle is essential for calculating the total number of combinations in scenarios where multiple choices are involved.

In this context, the customer has multiple independent choices: the type of drink (2 options), the size (4 options), and the flavor (5 options). The total number of combinations is found by multiplying the number of choices for each category, illustrating how different selections can be combined.

Multiplicative counting involves multiplying the number of choices available at each stage of decision-making. In this problem, the total number of drink orders is calculated by multiplying the number of drink types, sizes, and flavors, demonstrating how to systematically account for all possible outcomes.
