Final answer:
To find the number of possible kids' lunches, multiply the number of options for each component of the lunch using the multiplication principle. In this case, there are 3 options for the main dish, 2 options for the side dish, and 2 options for the drink, resulting in 12 possible kids' lunches.
Step-by-step explanation:
To find the number of possible kids' lunches, we need to count the number of options for each component of the lunch. Let's say there are 3 options for the main dish, 2 options for the side dish, and 2 options for the drink. We can use the multiplication principle to determine the total number of possible lunches. In this case, the number of possible kids' lunches would be 3 x 2 x 2 = 12. Therefore, there are 12 possible kids' lunches.
