Question

an ice cream store sells 4 drinks, in 4 sizes, and 5 flavors. in how many ways can a customer order a drink?
there are \\(\square\\) ways that the customer can order a drink.

Explanation:

Step1: Apply the fundamental counting principle

The fundamental counting principle states that if there are \(m\) ways to do one thing, \(n\) ways to do a second thing, and \(p\) ways to do a third thing, then the total number of ways to do all three things together is \(m\times n\times p\). Here, \(m = 4\) (number of drinks), \(n=4\) (number of sizes), and \(p = 5\) (number of flavors).

Step2: Calculate the product

We calculate \(4\times4\times5\). First, \(4\times4=16\), then \(16\times5 = 80\).

Answer:

\(80\)
