Q. Jordan is making an ice cream sandwich. There are

2

types of sandwich cookies and

2

types of ice cream to choose from. How many different ice cream sandwiches can Jordan make using exactly one of each item?

\newline

\_\_\_\_

ice cream sandwiches

Identify Choices: Identify the number of choices for each item. $\newline$ Jordan has $2$ types of sandwich cookies and $2$ types of ice cream to choose from.
Use Counting Principle: Use the fundamental counting principle. $\newline$ To find the total number of different combinations, multiply the number of choices for cookies by the number of choices for ice cream. $\newline$ $2$ types of cookies $\times$ $2$ types of ice cream = $4$ different ice cream sandwiches.
Verify Calculation: Verify the calculation. $\newline$ $2$ choices for the first item and $2$ choices for the second item should result in $2 \times 2 = 4$ combinations. There is no math error in the calculation.
